Does anyone know how Spotify assigns the genre tags to artists? Looking up myself on this site shows me as under two main tags: "Folk Rock Italiano" and "SLC Indie" (which is apparently Salt Lake City).

Although folk rock and indie are accurate, I'm neither Italian nor American.

For various reasons they are secretive about this, but the genre system is inherited from EchoNest which they acquired in 2014. EchoNest's main idea was to combine audio analysis with natural language processing and web scraping to categorize music. In fact the two founders were PhD's in each respective field.

But nowadays I'm guessing they are utilizing their huge dataset of playlists to group artists under tags. Obviously such systems will work better the more popular an artist is.

I wonder / kinda hope that they have a bunch of music experts working for them that manually categorize and tag music, at least to kickstart their algorithms.

They are not that secretive, it's been written about several times. Long story short: a lot of it is still Glenn McDonald, the person behind everynoise, that was acquihired when they bought echonest.

Here are a few articles about it (there are several more): https://artists.spotify.com/blog/how-spotify-discovers-the-g... https://www.thefader.com/2020/12/02/escape-room-genre-spotif... https://www.thestar.com/entertainment/2016/01/14/meet-the-ma...

Well, ideally your spotify artist page should contain the genres you're tagged with, along with some info of how that came to be, and even a way to request a change to those. But they don't want people to game the system, and also not let competitors know how they do things (I'm guessing).

At least you get the genre info is in the web API, just not present on the artist page (you need a token for the query to work, but you can create that on dev page): https://developer.spotify.com/console/get-artist/?id=10YNQq8...
