Every week, thousands of artists release albums on Spotify. Sifting through all this new music to find good stuff to listen to can be hard. Luckily, there are lots of tools from New Music Tuesday playlists to the Spotify Viral 50 to help us find the needles in the proverbial haystack of new music. However, most of these tools tend to surface up new music by artists that have been around for a while. For instance, the top artist on Spotify Viral 50 as I write this is Jeremih who has been on the charts for five years. The top of New Music Tuesday right now is Mumford & Sons who’ve been recording for at least eight years.
I’m interested in finding music by the freshest artists – artists that are at the very beginning of their recording careers. To that end, I’ve built a new chart called ‘The Fresh 40′ that shows the top albums by the freshest artists. To build The Fresh 40 I scour through all of the albums that have been released in the last two weeks on Spotify (on average that’s about 30 thousand albums), and find the albums that are the very first album release for its artist. I then rank each album by a weighted combination of the number of followers the artist has on Spotify and the popularity of the artist and album (which is related to Spotify track plays). The result is a chart of the top 40 most popular fresh artists.
The Fresh 40 updates every day and shows all the salient info including the rank, yesterday’s rank, the overall score, artist followers, artist popularity, album popularity and the number of days that the album has been on the chart. Since an album can only be on the chart for 15 days, there’s quite a bit of change from day to day.
If you are interested in finding music by the very newest artists on Spotify, you might be interested in The Fresh 40. Give the chart a look.

My weekend programming project this week was to explore a new feature of the Spotify Web API that allows you to find albums that have been released in the last two weeks. The result is a web app called Fresh Faces. This app goes through all of the recent releases and finds those that are the very first release for the artist. If you are looking for new music, there’s no fresher place to start than this app – it finds the newest music by the freshest artists – artists that are barely two weeks into their recording career.
Fresh Faces lets you sort the results based on artist popularity, album popularity, artist followers or release date. You can click on an album to hear a sample, find more info about the album or open it on Spotify.
How many new releases are there?
I was curious about how many releases there are in a two week period, and when releases tend to happen, so I added a chart at the bottom of the Fresh Faces app that shows the distribution of fresh and recurring releases and the dates when releases happen. You can see that the shift of releasing music from Tuesday to Friday is ongoing.
In the past two weeks about 32,000 albums have been released – about 5,200 of these are the first release for the artist. That’s a whole lot of fresh music.
Give Fresh Faces a try and let me know what you think.

One of the problems with working at a company like Spotify is that my Spotify account gets filled up with all sorts of work-related playlists. Over the last few years I’ve built lots of apps that create playlists. When I test these apps I end up generating lots of playlists that I will never ever listen to. If I were a tidy soul, I’d clean up my playlists after ever project, but, alas, that is something I never do. The result is that after working at Spotify for a year (and using Spotify for 8 years), I’ve accumulated many hundreds of garbage playlists. Now I could go into the Spotify desktop client and clean these up, but in the current client there’s no good way to bulk delete playlists. Each playlist delete takes at least 3 clicks. The prospect of doing this hundreds of times to clean up the playlist garbage is a bit overwhelming.
I had a few hours to kill in a coffeeshop yesterday so I decided to deal with my playlist mess. I wrote a little Spotify web app called The Unfollower that lets you unfollow any of your playlists with a single click. If you change your mind, you can re-follow any playlist that you unfollow.
The Unfollower uses the Spotify Web API to make it all happen. In particular it relies on the Follow/Unfollow API that was recently added by the API team.
If you are like me and have lots of dead playlists clogging up your Spotify, and you are looking for a streamlined way of cleaning them up, give The Unfollower a try.
There’s a strong connection between music and memory. Whenever I here the song Lovin You by Minnie Riperton, I’m instantly transported back to 1975 when I spent the summer apprenticed to Tom, my future brother-in-law, fixing electronic organs. I was 15, Tom was 22 and super cool. He had a business (New Hampshire Organ Service) and he had a van with an 8-track player and an FM radio (a rarity in 1975). As we drove between repairs across rural New Hampshire we’d pass the time by listening to the radio. Now, when I hear those radio songs from 1975 it is like I’m sitting in that van again.
Music can be like a time machine. Transporting us to different times in our lives. I was interested in exploring this a bit more. Inspired by @realtimewwii which gives a day-by-day account of World War II, I created a set of dynamically updating Spotify playlists that follow the charts week-by-week.
For example there’s the 50 Years Ago in Music playlist that contains the top 100 or songs that were on the chart 50 years ago. As I write this on April 12, 2015, this playlist is showing the top songs for the week of April 12, 1965.
The music on this playlist sends me back to when I was 5 years old listening to music on our AM radio in the kitchen in the morning while eating breakfast.
If you follow this playlist you’ll be able to re-create what it was like to listen to music 50 years ago. If the mid-sixties doesn’t speak to you musically, there are some other playlists that you can try.
There’s 40 Years Ago in Music that brings me back to 1975 on the road with Tom.
There’s 30 years Ago in Music which is currently playing music from the mid-80s like Madonna and Phil Collins.
There’s 20 Years Ago in Music currently playing music from the mid-90s:
10 Years Ago in Music plays the music that was on the radio when Spotify was just a gleam in Daniel’s eye.
5 Years Ago in Music – the playlist of @echonest in its heyday.
Yesterday I gave a talk at SXSW about what we can learn about how we listen to music by looking at all sorts of listener data that we collect at Spotify. You can see the slides for my talk here … but the slides only tell half the story, the other have are in my words, but those aren’t written down anywhere. You’ll just have to assume that they were very insightful, and a little bit humorous, but at the end told an incredible story leaving you inspired and fulfilled.

I just had a skype call with a group of young women called the Hippie Pandas, a First Lego League Team based in Rochester New York. As part of the First Lego League competition(*), they are working on a research project titled “How can we improve the way teachers learn to use music in the classroom to improve student’s performance and behavior.” In their research they found that particular types of music when played in the classroom can improve memorization, creativity and behavior. The team has created a website with a number of specialized Spotify playlists that teachers can use to enhance learning and behavior in the classroom.
For example, here’s a playlist that they’ve build for Focus and Memorization:
Here’s a playlist designed to Energize and Wake up the classroom.
The Hippie Pandas use audio attributes such as tempo and instrumentalness to create these task-appropriate playlists.
Like all good scientists the Hippie Pandas have tested their hypotheses. They have worked with a number of classroom teachers who are testing their contextual playlists with students in the classroom. Although they haven’t published any results yet, they’ve reported that the teachers have seen great improvements in the classroom when these task-appropriate playlists.
The Hippie Pandas have gone beyond creating playlists for teachers – they have also identified a number of barriers that would prevent music from being used in the classroom and are working to eliminate those barriers. For example, in many schools access to Spotify is blocked since, according to school administrators, Spotify doesn’t provide educational benefit. The HP team has been able to get access to Spotify restored in their local school district after demonstrating how music can improve student performance. Another barrier the Pandas have recognized is that not all teachers will have access to Spotify. To address this issue, the Pandas are lobbying Spotify to make free accounts available for all teachers. That sounds like a great idea to me.
In April, the Hippie Pandas journey to St. Louis to take part in the FIRST World Festival competition. They’ve competed in the world championships in previous years and have brought home a number of trophies and received special recognition for their project that could save lives. I think they will do well this year too. They’ve done quite a good job at identifying an opportunity for teachers to improve students behavior and performance in the classroom just by playing appropriate music. They are a smart, engaging group of young women who present their findings with energy and enthusiasm. I wish them well.
(*) For Inspiration and Recognition of Science and Technology (FIRST), is an organization that was founded by Dean Kamann in 1989 to inspire young people’s interest and participation in science and technology. The program is for students K-12 and the mission is to inspire young people to be science and technology leaders, by engaging them in exciting mentor-based programs that build science, engineering and technology skills, that inspire innovation, and that foster well-rounded life capabilities including self-confidence, communication, and leadership. The FIRST Lego League (FLL) introduces younger students (9-14) to real-world engineering challenges by buildingLEGO-based robots to complete tasks on a thematic playing surface and through a research and development project to solve a real world problem. Today there are over 28,000 FLL teams around the world. This years theme was called, World Class, learning unleashed
The Spotify Web API team pushed out a new feature recently that extends the search API to include playlist search. With this new feature it is now possible to search across all of the popular public playlists created by Spotify users. To try out the new search capability I created a new web app called The Playlist Miner.
The Playlist Miner is a web app that will create a Spotify playlist for you by finding the top songs in all of the playlists that match your criteria. Say, for example, that I want to create a dinner party playlist. First, I find the top playlists that match ‘dinner party’ with The Playlist Miner:
The Playlist Miner will find up to the top 1,000 most popular playlists that match dinner party. It shows them to me, giving me a chance to refine my query to focus in on the exact type of playlist that I am interested in.
For this first try, I see lots of Christmas-oriented playlists (‘Tis the Season after all), but since I’m looking for music for a post-holiday dinner party, I’d rather not have holiday music in the playlist. So I refine my query to find non-Christmas oriented dinner party playlists like so:
The resulting playlists are suitably non-Christmasy.
I like the look of these playlists so I hit the Find Top Tracks button and The Playlist Miner will scour through all of the matching playlists (290 of them in this case) and find the most frequently appearing tracks.
Once the top 100 tracks are found, I can save them to Spotify as my own playlist.
Selecting Prefer more distinctive labor and delivery tracks adjusts the track order for popularity so that tracks that are more distinctive to the particular playlist context will rise to the top. You can also use logical operators to focus in on the exact type of playlist you want to. You can search for “work out” OR workout NOT running to find workout playlists without running in their titles/descriptions.
Under the hood – The Playlist Miner uses lots of bits of the Spotify API – user authentication, playlist search, playlist reading, playlist saving and more. The app is a an API calling beast – aggregating all the tracks from a thousand playlists requires 1,000 API calls. It’s a testament to the Spotify Web API that it doesn’t even blink under the load. You can play with the code on github.
It’s fun to use The Playlist Miner to explore the quirkier aspects of how people listen to music. There are ironing playlists and sleeping baby playlists. There are playlists for getting psyched and playlists for Labor and Delivery. With the Playlist Miner you can pull from all the playlists created for a particular purpose and build your own. Give it a try.
