Learn about a new genre every day
Posted by Paul in code, genre, playlist, The Echo Nest on January 16, 2014
The Echo Nest knows about 800 genres of music (and that number is growing all the time). Among those 800 genres are ones that you already know about, like ‘jazz’,’rock’ and ‘classical’. But there are also hundreds of genres that you’ve probably never heard of. Genres like Filthstep, Dangdut or Skweee. Perhaps the best way to explore the genre space is via Every Noise at Once (built by Echo Nest genre-master Glenn McDonald). Every Noise At Once shows you the whole genre space, allowing you to explore the rich and varied universe of music. However, Every Noise at Once can be like drinking Champagne from a firehose – there’s just too much to take in all at once (it is, after all, every noise – at once). If you’d like to take a slower and more measured approach to learning about new music genres, you may be interested in Genre-A-Day.
Genre-A-Day is a web app that presents a new genre every day. Genre-A-Day tells you about the genre, shows you some representative artists for the genre, lets you explore similar genres, and lets you listen to music in the genre.
If you spend a few minutes every day reading about and listening to a new genre, after a few months you’ll be a much more well-rounded music listener, and after a few years your knowledge of genres will rival most musicologists’.
An easy way to make Genre-A-Day part of your daily routine is to follow @GenreADay on twitter. GenreADay will post a single tweet, once a day like so:
Under the hood – Genre-A-Day was built using the just released genre methods of The Echo Nest API. These methods allow you to get detailed info on the set of genres, the top artists for the genres, similar genres and so on. It also uses the super nifty genre presets in the playlist API that allow you to craft the genre-radio listener for someone who is new to the genre (core), for someone who is a long time listener of the genre (in rotation), or for someone looking for the newest music in that genre (emerging). The source code for Genre-A-Day is on github.
The Zero Button Music Player
Posted by Paul in music information retrieval, playlist, recommendation, research, The Echo Nest, zero ui on January 14, 2014
Ever since the release of the Sony Walkman 35 years ago, the play button has been the primary way we interact with music. Now the play button stands as the last barrier between a listener and their music. Read on to find out how we got here and where we are going next.
In the last 100 years, technology has played a major role in how we listen to and experience music. For instance, when I was coming of age musically, the new music technology was the Sony Walkman. With the Walkman, you could take your music with you anywhere. You were no longer tied to your living room record player to listen to your music. You no longer had to wait and hope that the DJ would play your favorite song when you were on the road. You could put your favorite songs on a tape and bring them with you and listen to them whenever you wanted to no matter where your were. The Sony Walkman really changed how we listened to music. It popularized the cassette format, which opened the door to casual music sharing by music fans. Music fans began creating mix tapes and sharing music with their friends. The playlist was reborn, music listening changed. All because of that one device.
We are once again in the middle of music+technology revolution. It started a dozen years ago with the first iPod and it continues now with devices like the iPhone combined with a music subscription service like Spotify, Rdio, Rhapsody or Deezer. Today, a music listener armed with an iPhone and a ten dollar-a-month music subscription is a couple of taps away from being able to listen to almost any song that has ever been recorded. All of this music choice is great for the music listener, but of course it brings its own problems. When I was listening to music on my Sony Walkman, I had 20 songs to choose from, but now I have millions of songs to choose from. What should I listen to next? The choices are overwhelming. The folks that run music subscription services realize that all of this choice for their listeners can be problematic. That’s why they are all working hard to add radio features like Rdio’s You.FM Personalized Radio. Personalized Radio simplifies the listening experience – instead of having to pick every song to play, the listener only needs to select one or two songs or artists and they will be presented with an endless mix of music that fits well with initial seeds.
Helping listeners pick music is especially important when you consider that not all music listeners are alike, and that most listeners are, at best, only casual music fans. A study conducted in 2003 and again in 2006 by Emap (A UK-based Advertising agency), summarized here by David Jennings, identified four main types of music listeners. Jennings describes these four main listening types as:
Savants – for whom everything in life is tied up with music
Enthusiasts – Music is a key part of life but is balanced with other interests
Casuals – Music plays a welcoming role, but other things are far more important
Indifferents – Would not lose much sleep if music ceased to exist.
These four listener categories are an interesting way to organize music listeners, but of course, real life isn’t so cut and dried. Listener categories change as life circumstances change (have a baby and you’ll likely become a much more casual music listener) and can even change based on context (a casual listener preparing for a long road-trip may act like a savant for a few days while she builds her perfect road-trip playlist).
In 2006, the distribution of people across these 4 categories was as follows:
This chart says a lot about the music world and why it works the way it does. For instance, it gives us a guide as to how much different segments of the listening world are willing to pay for music in a year. On the chart below, I’ve added my estimate of the amount of money each listener type will spend on music in a year.
Savants will spend a thousand dollars or more on vinyl, concerts, and music subscriptions. Enthusiasts will spend $100 a year on a music subscription or, perhaps, purchase a couple of new tracks per week. Casuals will spend $10 a year (maybe splurge and buy that new Beyoncé album), while Indifferents will spend nothing on music. This is why music services like Spotify and Rdio have been exploring the Fremium model. If they want to enroll the 72% of people who are Casual or Indifferent music listeners, they need a product that costs much less than the $100 a year Enthusiasts are willing to pay.
However, price isn’t the only challenge music services face in attracting the Casuals and the Indifferents. Different types of listeners have a different tolerance around the amount of time and effort it takes to play music that they want to listen to.
A music Savant – someone who lives, eats and breathes music – is happy spending hours a day poring through music blogs, forums and review sites to find new music, while the Indifferent music listener may not even make the simplest of efforts like turning the radio on or switching to a new station if they don’t like the current song. A simple metric for the time and effort spent is Interactions Per Listening Session. In this chart, I’ve added my estimate of the number of interactions, on average, a listener of a given type will tolerate to create a listening session.
Interactions per Listening Session is an indication of how many times the listener controls their music player for a listening session. That music Savant may carefully handpick each song going into a playlist after reading a few music blogs and reviews about an artist on The Hype Machine, checking out the artist bio and previewing a few tracks. The music Enthusiast may grab a few top songs from a handful of their favorite artists to build a Spotify playlist. The casual listener may fire up Pandora, select an artist station and click play, while the Indifferent music listener may passively listen to the music that is playing on the radio or in the background at the local Starbucks.
The above chart shows why a music service like Pandora has been so successful. With its simple interface, Pandora is able to better engage the Casual listeners who don’t want to spend time organizing their listening session. A Pandora listener need only pick a station, and Pandora does all the work from there. This is why music subscription services hoping to attract more users are working hard to add Pandora-like features. In order to make their service appeal to the Casuals, they need to make it incredibly easy to have a good listening experience.
But what about those Indifferents? If 40% of people are indifferent to music, is this a lost market for music services? Is it impossible to reach people who can’t even be bothered to queue up some music on Pandora? I don’t think so. Over the last 75 years, terrestrial radio has shown that even the most indifferent music fan can be coaxed into simple, “lean back” listening. Even with all of the media distractions in the world today, 92% of Americans age 12 or older listen to the radio at least weekly, much the same as it was back in 2003 (94%).
So what does it take to capture the ears of Indifferents? First, we have to drive the out-of-pocket costs to the listener to zero. This is already being done via the Freemium model – Ad supported Internet radio (non-on-demand) is becoming the standard entry point for music services. Next, and perhaps more difficult, we have to drive the number of interactions required to listen to music to zero.
Thus my current project – Zero UI – building a music player that minimizes the interactions necessary to get good music to play – a music player that can capture the attention of even the musically indifferent.
Implicit signals and context
Perhaps the biggest challenge in creating a Zero UI music player is how to get enough information about the listener to make good music choices. If a Casual or Indifferent listener can’t be bothered to explicitly tell us what kind of music they like, we have to try to figure it out based upon implicit signals. Luckily, a listener gives us all kinds of implicit signals that we can use to understand their music taste. Every time a listener adjusts the volume on the player, every time they skip a song, every time they search for an artist, or whenever they abandon a listening session, they are telling us a little bit about their music taste. In addition to the information we can glean from a listener’s implicit actions, there’s another source of data that we can use to help us understand a music listener. That’s the listener’s music listening device – i.e. their phone.
The mobile phone is now and will continue to be the primary way for people to interact with and experience music. My phone is connected to a music service with 25 million songs. It ‘knows’ in great detail what music I like and what I don’t like. It knows some basic info about me such as my age and sex. It knows where I am, and what I am doing – whether I’m working, driving, doing chores or just waking up. It knows my context – the time of day, the day of the week, today’s weather, and my schedule. It knows that I’m late for my upcoming lunch meeting and it even might even know the favorite music of the people I’m having lunch with.
Current music interfaces use very little of the extra context provided by the phone to aid in music exploration and discovery. In the Zero UI project, I’ll explore how all of this contextual information provided by the latest devices (and near future devices) can be incorporated into the music listening experience to help music listeners organize, explore, discover and manage their music listening. The goal is to create a music player that knows the best next song to play for you given your current context. No button pressing required.
There are lots of really interesting areas to explore:
Can we glean enough signal from the set of minimal listener inputs?
Which context types (user activity, location, time-of-day, etc.) are most important for scheduling music? Will we suffer from the curse of dimensionality with too many contexts?
What user demographic info is most useful for avoiding the cold start problem (age, sex, zip code)?
How can existing social data (Facebook likes, Twitter follows, social tags, existing playlists) be used to improve the listening experience?
How can we use information from new wearable devices such as the Jawbone’s Up, the Fitbit, and the Pebble Smart Watch to establish context?
How do we balance knowing enough about a listener to give them good music playlists and knowing so much about a listener that they are creeped out about their ‘stalker music player’?
Over the next few months I’ll be making regular posts about Zero-UI. I’ll share ideas, prototypes and maybe even some code. Feel free to follow along.
Six Degrees of Black Sabbath (v2)
Posted by Paul in code, fun, Music, The Echo Nest on January 6, 2014
For my Christmas vacation programming project this year, I revisited an old hack: Six Degrees of Black Sabbath. I wrote the original, way back in 2010 at the very first San Francisco Music Hack Day. That version is still up and running, and getting regular visits, but it is getting a bit long in the tooth and so I’ve given it a total rewrite from the ground up. The result is the new Six Degrees of Black Sabbath:
Six Degrees of Black Sabbath is like the Oracle of Bacon but for music. It lets you find connections to just about any two artists based upon their collaborations. Type in the name of two artists, and 6dobs will give you a pathway showing the connections that will get you from one artist to another. For instance, if you enter ‘The Beatles’ and ‘Norah Jones’ you’ll get a path like:
- We start with The Beatles
- The Beatles had member George Harrison
- George Harrison performed with Ravi Shankar on the song Bangla Dhun and 26 others.
- Ravi Shankar was parent of Norah Jones
If you don’t like a particular connection, you can bypass it generating a new path. For instance, if we bypass Ravi Shankar, it will take us eight steps to get to Norah Jones from the Beatles:
The Beatles -> Paul McCartney -> The Fireman -> Youth -> Pigface
-> Mike Dillon ->Garage A Trois -> Charlie Hunter -> Norah Jones
Not all connections are created equal. Mick Jagger and Keith Richards have been playing together for over 50 years in the Rolling Stones. That’s a much stronger connection than the one between Mick Jagger and Fergie for performing a single song together at the Rock and Roll Hall of Fame. We take these connection strengths into account when finding paths between artists. Preference is given to stronger connections, even if those stronger connections will yield a longer path.
The new version of Six Degrees of Black Sabbath has a number of new features:
Video – Each step in a path is represented by a Youtube video – often with a video by the two artists that represent that step. I’m quite pleased at how well the video works for establishing the connection between two artists. Youtube seems to have it all.
Live stats – The app tracks and reports all sorts of things such as the longest path discovered so far, the most frequently occurring artists on paths, the most connected artists, most searched for artists and so on.
Larger database of connections – the database has about a quarter million artists and 2.5 million artist-to-artist connections.
Autocomplete for artist names – no need to try to remember how to spell ‘Britney Spears‘ – just start typing the parts you know and it will sort it out.
Spiffier looking UI – It still looks like it was designed by an engineer, but at least it looks like it was designed in this decade by an engineer.
Path finding improvements – faster and better paths throughout.
Revisiting this app after 4 years was a lot of fun. I got to dive deep into a bunch of tech that was new to me including Redis, Bootstrap 3, and the YouTube video search API. I spent many hours untangling the various connections in the new Musicbrainz schema. I took a tour through a number of Pythonic network graph libraries (Networkx, igraph and graph-tool), I learned a lot about Python garbage collection when you have a 2.5gb heap.
Give the app a try and let me know what you think.
Million Song Shuffle
Back in 2001 when the first iPod was released, Shuffle Play was all the rage. Your iPod had your 1,000 favorite songs on it, so picking songs at random to play created a pretty good music listening experience. Today, however, we don’t have 1,000 songs in our pocket. With music services like Rdio, Rhapsody or Spotify, we are walking around with millions of songs in our pocket. I’ve often wondered what it would be like to use Shuffle Play when you have millions of songs to shuffle through. Would it be a totally horrible listening experience listening to artists that are so far down the long tail that they don’t even know that they are part of a dog? Would you suffer from terminal iPod whiplash as you are jerked between Japanese teen pop and a John Philip Sousa march?
To answer these questions, I built an app called Million Song Shuffle. This app will create a playlist by randomly selecting songs from a pool of many millions of songs. It draws from the Rdio collection and if you are an Rdio user you can hear listen to the full tracks.
The app also takes advantage of a nifty new set of data returned by the Echo Nest API. It shows you the absolute hotttnesss rank for the song and the artist, so you will always know how deep you are into the long tail (answer: almost always, very deep).
So how is listening to millions of songs at random? Surprisingly, it’s not too bad. The playlist certainly gets a high score for eclecticism and surprise, and most of the time the music is quite listenable. But give it a try, and form your own opinion.
Its fun, too, to see how long you can listen to the Million Song Shuffle before you encounter a song or even an artist that you’ve heard of before. If the artist is not in the top 5K artists, it is likely you’ve never heard of them. After listening to Million Song Shuffle for a little while you start to get an idea of how much music there is out there. There’s a lot.
For the ultimate eclectic music listening experience, try the Million Song Shuffle.
Have a Very Nestive Christmas
Posted by Paul in code, Music, playlist, The Echo Nest on December 19, 2013
We are approaching peak Christmas music season. That means that many of us are getting really sick of hearing the same Christmas songs over and over. One can only hear Bing Crosby’s White Christmas so many times before measures must be taken. To remedy this situation, this morning I created a quick web app that let you chose from among a number of different Christmas genres (from classical to heavy metal) to let you add a little variety to your Christmas mix. If you are getting weary of the Christmas standards, but still want to listen to Christmas music, you may want to give it a try: The Christmas Playlister
Attention Deficit Radio
Posted by Paul in code, data, events, fun, hacking, music hack day, The Echo Nest on December 8, 2013
This weekend, I’ve been in London, attending the London Music Hack Day. For this weekend’s hack, I was inspired by daughter’s music listening behavior – when she listens to music, she is good for the first verse or two and the chorus, but after that, she’s on to the next song. She probably has never heard a bridge. So for my daughter, and folks like her with short attention spans, I’ve built Attention Deficit Radio. ADR creates a Pandora-like radio station based upon a seed artist, but doesn’t bother you by playing whole songs. Instead, after about 30 seconds or so, it is on to the next song. The nifty bit is that ADR will try to beat-match and crossfade between the songs giving you a (hopefully) seamless listening experience as you fly through the playlist. Of course those with short attention spans need something to look at while listening, so ADR has lots of gauges that show the radio status – it shows the current beat, the status of the cross-fade, tempo and song loading status.
There may be a few rough edges, and the paint is not yet dry, but give Attention Deficit Radio a try if you have a short listening attention span.
Who are the shallowest artists?
Posted by Paul in data, Music, The Echo Nest on November 25, 2013
Yesterday, I wrote about who the Deepest Artists are. So naturally, today I’ll turn that on its head and take a look at who are the Shallowest Artists. I define a shallow artist as an artist that despite having a substantial number of released songs, has most listens concentrated in their top five tracks. These are the artists that are best known for just a small number of songs.
For each artist, I’ve calculated a Shallowness Score which is merely the percentage of an artist’s plays that occurs in an artist’s top 5 songs. A Shallowness Score of 71% means that 71% of all listens occur in the top 5 songs. Thus, 71% of all listens to Survivor (of Eye of the Tiger fame) are found in their top 5 songs.
Update: This post used to reference the Pitch Perfect Treblemakers, but Glenn points to an ambiguous artist issue with the Treblemakers where multiple artists were conflated. The Pitch Pefect Treblemakers only have 4 songs so they are no longer a candidate for this list.
Here are the top 15 Shallowest Artists. Click to see the full chart:
As you’d expect, there are plenty of new artists on the list, artists like Icona Pop, Avicii and Zedd that have had a few charting songs. Being tagged as a shallow artist isn’t necessarily bad, it just means that your music is dominated by a handful of hits. That’s why we find Adele and Jeff Buckley on the same list as Paris Hilton and Smash Mouth.
Check out the full list of the Shallowest Artists as well as the full list of the Deepest Artists.
Who are the deepest artists?
Posted by Paul in data, fun, Music, The Echo Nest on November 24, 2013
Our playlists our filled with One Hit Wonders like My Sharona, Tainted Love and Final Countdown. One Hit wonders are the non-nutritious food of the music world – they are Twinkie’s, the Ho Hos and the Yodels of our musical diet. But what should we listen to when we want a full and nutritious musical meal? We should look for music by artists that have deeper catalogs – artists where the fans spend substantial time listening to the non-hits. These are the Deep Artists, the opposite of the One Hit Wonders – the artists that you can spend months or years listening to and exploring their collection.
Unfortunately, there’s no master list of Deep Artists – but I have lots of music listener data, so I figured I could build one. Here’s what I did. First I restricted my results to somewhat familiar artists with at least 100 songs in their catalog. I then scored each artist by the percentage of song plays that occur in the deep catalog versus the total plays for the artist – where deep catalog means a song that is not in the top ten for that artist. This gives each artist a Deepness Score that I could then use to sort artists to give us a list of the Deepest Artists. Here are the top ten:
Not surprising to see Johann Sebastian Bach at number two. Bach has no real ‘hits’ – and indeed has an incredibly deep catalog. 90% of all Bach plays occur in Bach’s non-top 10. The number one deep artist is Vitamin String Quartet – they have 3500 covers of songs with no clear hits among them.
Looking at the full list we see jam bands like Phish and Grateful Dead, AOR staples like Pink Floyd and David Bowie.
I’ve built a list of a little over 500 of the Deepest Artists. These are artists that have a deepness score of 50% or greater – meaning that at least 50% of all listens for the artist is in the deeper cuts. This Thanksgiving if you are looking for some more nutritious music, stay away from Alice’s Restaurant and other One Hit Wonders and listen to music by artists on this Deep Artists list.
Update: Glenn looked at these results and felt that a nutritious music meal shouldn’t include Vitamin String Quartet (it’s the ‘artificially-fortified sugar-coated cereal of music’ according to Glenn), so Glenn took a different approach with different results. Glenn calls his results boring, but I think they are quite interesting. Read his post: Good Boring results
Revisiting The Long Tail
Posted by Paul in data, The Echo Nest on November 23, 2013
It has been nearly 10 years since Chris Anderson’s Wired article and subsequent book called The Long Tail. In the article, book, and subsequent blog posts Chris (and I can call him Chris because we once had a 3 minute conversation in Bilbao Spain, so we are friends) showed data about how music listening is changing as we move away from the physical constraints of CD shelves and replace them with the infinite virtual shelves of the online music store.
I thought it was time to look at the data again to see if the trends that my good friend Chris was seeing back in 2004 still persist today. In particular, in the blog post Latest Rhapsody data and more Chris showed how a substantial fraction of the music market is shifting away from the Walmart inventory of the top 50,000 tracks:
This chart shows that as Rhapsody’s collection size increased the amount of listener market share in the songs that were not in the top 50K grew from 26%, to 28% and then 30% over 3 years. Today’s music subscription services boast 10 million or more songs (but of course, those numbers start to get a bit meaningless beyond a certain point – it becomes filler). Let’s take a look to see if the fraction of listening that is not in the top 50K tracks has continued to grow. Here’s some pie:
This data shows that in 2013, with 10million+ tracks available, 42% of listens can be found in the long tail (i.e. beyond the top 50K tracks). So the trend has continued. More listening is taking place in less popular music.
In the same blog post, my pal Chris presents this Hitland vs. nicheland chart that shows what percentage of the music business is selling the top 100 artists. Back in 2006, 50% of Walmart’s music business was selling music by the top 100 artists, while for Rhapsody, about 25% of market share was in the top 100 artists.
Lets’s extend this chart using listening data from 2013:
As you can see, the trend continues, only 20% of listening is in the top 100 artists. It’s not a dramatic change, but it does show that the more music you make available, the deeper the catalog, the deeper the listening.
Here are a few more fun facts about today’s listening. 80% of all listening is concentrated in the top 5,000 artists. The top 1,000 songs account for about 13% of all listening, and 80% of all listening is spread over about 222,0000 songs.
My good buddy Chris’s Long Tail hypothesis has come under considerable scrutiny in the last few years, but by looking at the data we see that the trends Chris pointed out have continued. Our listening is less concentrated in the hits than ever before. Yes, hits are important and will alway be, but if you make more music available to listeners, they will indeed listen to it. So, remember my best friend’s three rules for the Long Tail:
- Make everything available
- Cut the price in half – now lower it
- Help me find it.
At The Echo Nest, we work hard to make rule 3 a reality – our mission is to help connect people with the best music, whether it be in the short head, or deep into that Long Tail.
Children of the Hack (Angry Birds Edition)
Posted by Paul in data, events, hacking, Music, music hack day, The Echo Nest on November 18, 2013
I’m writing this post from Espoo Finland which is home to three disruptive brands: Nokia, who revolutionized the mobile phone market in the 1990s with its GSM technology; Rovio, who brought casual gaming to the world with Angry Birds; and Children of Bodom perhaps one of the most well known melodic death metal bands. So it is not surprising that Espoo is a place where you will find a mix of high tech, playfulness and hard core music – which is exactly what I found this past weekend at the Helsinki Music Hack Day hosted at the Startup Sauna in Espoo Finland.
At the Helsinki Music Hack Day, dozens of developers gathered to combine their interest in tech and their passion for music in a 24 hour hacking session to build something that was music related. Representatives from tech companies such as SoundCloud, Spotify and The Echo Nest joined the hackers to provide information about their technologies and guidance in how to use their APIs.
After 24 hours, a dozen hacks were demoed in the hour-long demo session. There was a wide range of really interesting hacks. Some of my favorites are highlighted here:
Cacophony – A multi-user remote touch controlled beat data sequencer. This hack used the Echo Nest (via the nifty new SoundCloud/Echo Nest bridge that Erik and I built on the way to Espoo), to analyze music and then allow you to use the beats from the analyzed song to create a 16 step sequencer. The sequencer can be controlled remotely via a web interface that runs on an iPad. This was a really nice hack, the resulting sequences sounded great. The developer, Pekka Toiminen used music from his own band Different Toiminen which has just released their first album. You can see the band and Pekka in the video:[youtube http://www.youtube.com/watch?v=nLwrTf5JQ5U]
It was great getting to talk to Pekka, I hope he takes his hack further and makes an interactive album for his band.
Hackface & Hackscan – by hugovk – This is a pretty novel set of hacks. Hackface takes the the top 100 or 1000 artists from your listening history on Last.fm, finds photos of the artists (via the Echo Nest API), detects faces using a face detection algorithm, intelligently resizes them and composites them into a single image giving you an image of what your average music artist in your listening history looks like.
Hackscan – takes a video and summarizes it intelligently into a single image by extracting single columns of pixels from each frame. The result is a crazy looking image that captures the essence of the video.
Hugo was a neat guy with really creative ideas. I was happy to get to know him.
Stronger Harder Faster Jester – Tuomas Ahva and Valtteri Wikstrom built the first juggling music hack that I’ve seen in the many hundreds of hack demos I’ve witnessed over the years. Their hack used three bluetooth-enabled balls that when thrown triggered music samples.
The juggler juggles the balls in time with the music and the ball tossing triggers music samples that align with the music. The Echo Nest analysis is used to extract the salient pitch info for the aligment. It was a really original idea and great fun to watch and listen to. This hack won the Echo Nest prize.
µstify – This is the classic boy meets girl story. Young man at his first hackathon meets a young woman during the opening hours of the hackathon.
They decide to join forces and build a hack (It’s Instagram for Music!) and two days later they are winning the hackathon! Alexandra and Arian built a nifty hack that builds image filters (in the style of Instagram) based upon what the music sounds like. They use The Echo Nest to extract all sorts of music parameters and use these to select image filters. Check out their nifty presentation.
Gig Voter – this Spotify app provides a way for fans to get their favorite artists to come to their town. Fans from a town express an interest in an artist. Artists get a tool or helping them plan their tour based on information about where their most active fans actually are as well as helping them sell gigs to location owners by being able to prove that there is demand for them to perform at a certain location. Gig Voter uses Echo Nest data to help with the search and filtering.
Hit factory – Hit Factory is a generative music system that creates music based upon your SoundCloud tastes and adapts that music based upon your feedback . Unfortunately, no samples of the music are to be found online, but take my word, they were quite interesting – not your usual slightly structured noise.
Abelton Common Denominator – a minimal, mini-moog style interface to simplify the interaction with Abelton – by Spotify’s Rikard Jonsson.
Swap the Drop – this was my hack. You can read more about it here.
One unusual aspect of this Music Hack Day was that a couple of teams that encountered problems and were unable to finish their hacks still got up and talked about their failures. It was pretty neat to see hardcore developers get up in front of a room full of their peers and talk about why they couldn’t get Hadoop to work on their terrabyte dataset or get their party playlister based on Meteor to run inside Spotify.
I’ve enjoyed my time in Espoo and Helsinki. The Hack Day was really well run. It was held in a perfect hacking facility called the Startup Sauna.
There was plenty of comfortable hacking spots, great wifi, and a perfect A/V setup.
The organizers kept us fed with great food (Salmon for lunch!), great music, including a live performance by Anni.
There was plenty of Angry Birds Soda.
Many interesting folks to talk to …
Thanks to Lulit and the rest of the Aaltoes team for putting together such a great event.
