The Playlist Miner
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.
The Million Songs of Christmas
No other holiday dominates our listening like Christmas. During this season, we are exposed to a seemingly never ending playlist of Christmas music. So its no surprise that there’s a huge amount of Christmas music available on Spotify. How much? Let’s take a look.
How much Christmas music is there?
It is actually quite hard to pinpoint the exact number of Christmas songs. First, every week during the holiday season thousands more Christmas songs are added to the set. Second, some songs are seasonal – is Frosty The Snowman a Christmas song? Not literally, but it gets a lot of play at this time of year, even by the antipodes. Finally, there are a number of other holidays and celebrations at this time of year such as Hanukkah, Boxing Day, New Years, Kwanzaa, the Winter Solstice, and Festivus that we want to include in this category. So when I say “Christmas Music” I’m referring to western music that is played primarily during December. There’s probably a better term to describe this music, but terms like seasonal, and holiday have their own special baggage – perhaps something like music coincident with the northern hemispheric winter solstice is the most precise description, but lets stick with Christmas music just to keep things simple. So how much Christmas music is there? In early December 2014, crack music + data nerd Aaron Daubman dove into the Spotify + Echo Nest music catalog and found 914,047 Christmas tracks – that’s just under a million Christmas tracks. Let’s unwrap this dataset to see what we can find.
First, some basic stats: Those 914,047 tracks represent 180,660 unique songs and were created by 63,711 unique artists – from Aaron Neville to Zuma the King. The top 20 artists with the most Christmas tracks in the Spotify catalog are all pre-Beatles artists:
Artists with the most Christmas Tracks
# | Name | Count |
---|---|---|
1 | Bing Crosby | 22382 |
2 | Frank Sinatra | 17979 |
3 | Elvis Presley | 12381 |
4 | Nat King Cole | 11613 |
5 | Johann Sebastian Bach | 8958 |
6 | Dean Martin | 8000 |
7 | Perry Como | 7529 |
8 | Ella Fitzgerald | 6428 |
9 | Mahalia Jackson | 5883 |
10 | Mario Lanza | 5377 |
11 | Johnny Mathis | 5036 |
12 | Rosemary Clooney | 4538 |
13 | Peggy Lee | 4450 |
14 | Harry Belafonte | 4054 |
15 | The Andrews Sisters | 3567 |
16 | Louis Armstrong | 3481 |
17 | Gene Autry | 3411 |
18 | Doris Day | 2985 |
19 | Pat Boone | 2767 |
20 | Connie Francis | 2500 |
Yes, that’s right, Bing Crosby has 22,382 different Christmas tracks (!) in the Spotify catalog. Now, a little digression on what we consider to be a unique track. Music, especially popular music, is released in many forms. A very popular song, such as Bing Crosby’s White Christmas, may appear on a wide range of albums – from the original studio release to a plethora of Christmas Compilations and artist ‘best of’ albums. Each of these track releases may have different album art, different rights holders and regional licenses. Thus, even though the audio for White Christmas may be the same on each of the release, we consider each release as a different track.
White Christmas
Let’s take a closer look at Bing Crosby’s White Christmas. In our catalog of nearly a million Christmas tracks, 2,196 of them are Bing Crosby’s classic. I’ll say that again, just because it is a rather phenomenal fact – there are 2,196 different albums on Spotify that contain Bing’s White Christmas. It is hard to believe, so I created a web page that contains all 2,196 of the albums so you can see them all. Click on the image below to load them all up (warning – with 2000+ album covers it’s a bit of a browser buster).
White Christmas isn’t the only uber-track of the holidays. Here are the top 25 Christmas tracks based upon the number of times they have been released on an album:

So there are lots of copies of Bing Crosby’s White Christmas and Eartha Kitt’s Santa Baby out there – but what are the most common Christmas songs overall? Which ones have been recorded the most by any artist? The following table shows the top 25:

Of course this data may be confounded by the uber-tracks like White Christmas that have thousands of versions by a single artist, so lets look at the most recorded songs by unique artists – that is, we only count Bing Crosby once for White Christmas instead of 2,196 times. When we do that the top 25 changes a bit:

The songs in green are the songs that are unique to each list.
Artists with the most number of unique songs
Bing Crosby is at the top of the Most Christmasy artists mainly because of the widespread re-issuing of White Christmas. But if we look at unique songs (i.e. White Christmas only counts once for Bing Crosby), the top Christmas artists look very different – with classical composers, Karaoke ‘artists’ and music factories topping the charts:
Artists with the most number of unique songs
1 | Johann Sebastian Bach | 3681 |
2 | Bing Crosby | 1462 |

Current popular Christmas crooner Michael Bublé, with 31 unique Christmas songs has a way to go before he makes it on to the most-unique-songs-recorded chart.
Speaking of Karaoke – there’s lots of Christmas Karaoke – 23,472 tracks to be precise. The top 25 Karaoke songs are the classics:

Top Terms
We can build a good list of seasonal terms by finding the most frequently occurring words in song titles. Here are the top 75 or so, as a word cloud created by wordle (stop words are removed of course).
Longest Christmas song name
There are lots of very long song names in the set of Christmas songs – the longest is this Christmas medly.
A great song for testing how well your music player UI deals with unusual titles.
Conclusion
One would think that with a million Christmas tracks we’d already have more than enough Christmas music – but, it seems, we still like new Christmas music. Ariana Grande’s recently released Santa Tell Me is climbing the streaming charts (currently #44 at charts.spotify.com).
Plus, there’s seemingly no-end to the variety of Christmas Music. If White Christmas with Bing Crosby is not your style, then there’s Blue Christmas by Elvis.
And If that’s not your thing, maybe you’ll enjoy Red Christmas by Insane Clown Posse.
The Mobile Infinite Jukebox Survey results
Over the last six months or so The Infinite Jukebox had a link to a survey about features peopled would like to see in a mobile version of The Infinite Jukebox. Since then, over 10,000 people have taken the survey. Here are the results.
The survey was linked to directly from the Infinite Jukebox. The questions asked were:
Since the text in link to the survey was “Interested in a mobile version of the Infinite Jukebox? Then take this one minute survey” it is no surprise that 99% of all respondents are interested in a mobile version of the app.
The split between Android and iOS aligns with other iOS vs Android metrics out there on the webs.
As for how much people would be willing to pay, 64% would be willing to pay something for the app.
This was a bit surprising – 70% of folks want to play music from their own collection, and only 11% are interested in playing music from a streaming service like Spotify or Rdio.
The final question was an open-ended question asking about what other features would you like to see in the Infinite Jukebox. Many of the responses were about what features would like to see in the current web version, while many were about what features should be in a mobile version. Some of the more common results are here:
Common new feature suggestions
- Background playing
- Offline playling
- No Ads
- Simple tuning options
- Playlist support
- Choose song length
- Time limits per song
- Infinitise multiple songs
- Color schemes
- Volume controls
- Social features (voting on best tunings)
So, you may be wondering where is the mobile version of the Infinite Jukebox? It is coming along, all the hard coding bits are done, but it has been very much a spare time project. I do hope to release it sometime in the near future. Here’s a short clip of the app in action:

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:
[spotify spotify:user:plamere:playlist:7EOwcqcYhCDsrvoutSVP9E]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
[spotify spotify:user:plamere:playlist:26fUkb0ZQdg62IY497OdNL]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.
It 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
Outside Lands lineup
I’m on my way to Outside Hacks – a hackathon tied in with the Outside Lands music festival. Since many hacks at the hackathon will be related to the festival it is pretty important to have a machine-readable version of the artist lineup for the festival. However, I couldn’t find any online. Since I had an hour in the airport lounge, and the airport actually has decent WiFi, I thought I would try to be a good hacker citizen and generate an easily parseable lineup.
A little python + some BeautifulSoup and a bit of Echo Nest Rosetta Data and I have created an Outside Lands lineup JSON that includes links to artist pages, plus Echo Nest, Spotify and Rdio IDs. The JSON is hosted online at:
http://static.echonest.com/OutsideLands/lineup_2014.json
Here’s the code:
It’s about time to get on the plane. If you can think of other interesting data to add to the lineup json let me know and I’ll try to add it before the hackathon.
