How the Spotify algorithm actually works
Spotify’s algorithm combines collaborative filtering, audio analysis, and web crawling to match songs with listeners most likely to enjoy them. Understanding these elements helps you target the right audience and improve your chances of playlist placement.

Hey friends!
Today we’re going to briefly talk about how Spotify’s algorithm actually works, and how you can take advantage of it to promote your music.
Here it is:
Collaborative filtering: Spotify looks at who listened and engaged, and cross references what they have in common and also like. To simplify this, if 8/10 people who listen to band A also like band B, you should probably show band B to the remaining 2/10 that don’t know them yet. Now do this across millions of artists and listeners…
Audio analysis: Spotify looks at the raw audio of the song and tries to figure out what it is, and who it’s for. This includes BPM, key, but also ‘danceability’ and other cool metrics.
Web crawling: Spotify looks at thousands of websites to see which artists are being talked about next to each other.
Collaborative filtering is the biggest one. By driving people who like your type of music to check out your song and engage with it in a positive manner, you can train Spotify to know who to recommend to.
We even figured out how many streams / listeners you need to do this for certain algorithmic playlists. In the past we used to say 2,500 streams for Release Radar and 10k streams for Discover Weekly. But we recently refreshed these numbers!
This is actually a sneak peek of a study we ran, the video about this along with the extensive data is coming later this week.
To summarize, a popularity index (this is an internal metric used by Spotify to gauge how popular a song is) of 20 on Spotify is roughly what you need to hit Release Radar’s algorithmic push and a 30 is need for Discover Weekly. These are averages, but they’ve held pretty true over the past few years.
The amount of streams and listeners to hit these algorithmic pushes has gotten harder over the past few years though. However, now you know what to aim for. Hit about 3,800 in the first few weeks to get a Release Radar push, and about 13,000 for a Discover Weekly push.
Keep mind though that Radio on Spotify has become much more prominent over the past few years. Our study goes into this as well, more on that in the near future!
Now, if you want to see myself, Jesse Cannon, Matt Bacon and Dustin Boyer talk about the Spotify algorithm check out the episode we uploaded last week about this:
We also discuss if the algorithm is anti-art. But knowing what you know now about how the algorithm works, and how it’s job is basically just to match your song with who is mostly likely to enjoy it - you know that the algorithm is NOT anti-art.
Anyways, enjoy and talk soon!
