The Ultimate Thanksgiving Playlist

On the annual drive to Thanksgiving dinner I’ve tortured my family with Alice’s Restaurant too many times over the years. Arlo Guthrie’s classic is still, in my mind, the classic Thanksgiving song, but there has to be more. So this year, I set out to expand my repertoire of Thanksgiving music – to build the ultimate Thanksgiving playlist. To do so, I looked through the top 300 or so most listened to Thanksgiving playlists on Spotify and found the top 100 songs that most frequently appear in all of these playlists, after discounting for popularity. Here are the results: The Ultimate Thanksgiving Playlist:

This is six hours of Thanksgiving music. All the classics are there, from Alice’s Restaurant to We are going to be Friends by the White Stripes.  It should get you through the Thanksgiving drive, the meal, dessert and maybe even an after dinner snack.

However, if you want to synchronize your cooking and your music listening, there’s no better way then to hop on over to Time For Turkey for your basting+music needs.

And since the Christmas season starts immediately after the last piece of pumpkin pie has been consumed, lets not waste time breaking out the Christmas playlist. Here are the top 100 songs appearing across the most popular 1,000 Christmas playlists: Top Christmas Songs

How Students Listen

The Spotify Insights team took a deep dive into some of the listening data of college students to see if there were any differences in how students at different schools listen. We looked at a wide range of data including what artists were played, what songs were played and when, what playlists played, what genres were played and so on. We focused mostly on looking for distinctive listening patterns and behaviors at the different schools. The results were a set of infographic style visualizations that summarize the distinctive listening patterns for each school.

How_Students_Listen_and_weezerIt was a fun study to do and really shows how much we learn about listening behavior based upon music streaming behavior.  Read about the study on the Spotify Insights Blog:  Top 40 Musical Universities in America:How Students Listen

More on “Where’s the Drama?”

My Music Hack Day Berlin hack was “Where’s the Drama?” – a web app that automatically identifies the most dramatic moment in any song and plays it for you. I’ve been having lots of fun playing with it … and even though (or perhaps because) I know how it works, I’m often surprised at how well it does at finding the most dramatic moments.  Here are some examples:

How does it work? The app grabs the detailed audio analysis for the song from The Echo Nest.  This includes a detailed loudness map of the song. This is the data I use to find the drama.  To do so, I look for the part of the song with the largest rise in volume over the course of a 30 second window (longer songs can have a bit of a longer dramatic window). I give extra weight to crescendos that culminate in louder peaks (so if there are two crescendos that are 20dB in range but one ends at 5dB louder, it will win). Once I identify the most dynamic part of a song, I pad it a bit (so we get to hear a bit of the drop after the build).

The rest is just UI – the song gets plotted as a heavily filtered loudness curve with the dramatic passage highlighted. I plot things with Highcharts, which is a pretty nifty javascript plotting and charting library. I recommend.

 Where_is_the_Drama_

Playing the music – I wanted to use Spotify to play the music, which was a bit problematic since there currently isn’t a way to play full streams with the Spotify Web API, so I did a couple of hacky hacks that got me pretty far. First of all, I discovered that you can add a time offset to a Spotify URI like so:

        

When this URI is opened in Spotify (even when opened via a browser), Spotify will start to play the song a the 1:05 time offset.  

I still needed to be able to stop playing the track – and there’s no way to do that directly – so instead, I just open the URI:

      

which happens to be the URI for John Cage’s 4’33.  In other words, to stop playing one track, I just start playing another (that happens to be silent).  The awesome side effect of this is that I’ll be slowly turning anyone who uses “Where’s the Drama?” into experimental music listeners as the Spotify recommendation system responds to all of those John Cage ‘plays’. This should win some sort of ‘hackiest hack of the year’ award.

It was a fun hack to make, and great fun to demo. And now that I have the app, I am no longer wasting time listening to song intros and outros, I can just get to the bit of the song that matters the most.

Acrostify – make Spotify playlists with embedded secret messages

For my summer vacation early-morning coding for fun project I revamped my old Acrostic Playlist Maker to work with Spotify.  The app, called Acrostify, will generate acrostic playlists with the first letter of each song in the playlist spelling out a secret message.  With the app, you can create acrostic playlists and save them to Spotify.

The app was built using The Echo Nest and Spotify APIs. The source is on github.

Give it a try at Acrostify.

Outside Lands Recommendations

I am at Outside Hacks this weekend – A hackathon associated with the Outside Lands music festival. For this hack I thought it would be fun to try out the brand new Your Music Library endpoints in the Spotify Web API. These endpoints let you inspect and manipulate the tracks that a user has saved to their music. Since the hackathon is all about building apps for a music festival, it seems natural to create a web app that gives you festival artist recommendations based upon your Spotify saved tracks. The result is the Outside Lands Recommender:

 

Your_Outside_Lands_Festival_Recommendations

 

The Recommender works by pulling in all the saved tracks from your Spotify ‘Your Music’ collection, aggregating the artists and then using the Echo Nest Artist Similar API to find festival artists that match or are similar to those artists. The Spotify API is then used to retrieve artist images and audio samples for the recommendations where they are presented in all of their bootstrap glory.

This was a pretty straight forward app, which was good since I only had about half the normal hacking time for a weekend hackathon. I spent the other half of the time building a festival dataset for hackers to use (as well as answering lots of questions about both the Spotify and Echo Nest APIs).

It has been a very fun hackathon. It is extremely well organized, the Weebly location is fantastic, and the quality of hackers is very high. I’ve already seen some fantastic looking hacks and we are still a few hours from demo time.  Plus, this happened.

Fetching my saved tracks from Spotify

The @SpotifyPlatform team just pushed out an update to the Spotify Web API that lets a developer retrieve and manipulate the tracks that a user has saved in ‘Your Music’. To show off this new functionality I wrote a quick demo that shows how to fetch the saved tracks for a Spotify user via the nifty new API.  The demo will first solicit permission from the user, and if the user grants such permissions, the app will then retrieved the saved tracks and show them as a simple list.

The demo is on line here: My Saved Tracks and the source is on github.

Set Listener update – now listen to specific shows in Spotify

Last month I released the Set Listener –  a web app that lets you create a Spotify playlist for an artist’s most recent show.   A frequent request by users has been to allow the creation of a Spotify playlist for any show, not just the most recent one. However, I didn’t want to have to implement an elaborate event search and browse feature (this was supposed to be a quick hack) especially since SetList.fm already implements this browsing. So instead I did a bit of hack to implement this feature – in addition to accepting an artist name, the Set Listener will accept the url of any setlist.fm show. If you enter a setlist.fm show URL, the Set Listener will grab the songs for that show and generate the playlist. Here’s the flow:

Go to setlist.fm and browse until you find your show of interest. Grab the URL

God_Is_an_Astronaut_Concert_Setlist_at_Melnā_Piektdiena__Riga_on_May_19__2014___setlist_fm

 

Paste the URL into the Set Listener and you should be good to go:
