Spotify for Artists has crunched the numbers on fan behavior and come up with 15 takeaways. Did you know EDM and country fans buy the most hats?

Spotify’s “Fan Study” digs into global listening trends and buying habits and provides recommendations on how to leverage the information.

Among the observations: Latin America is where fans are most open to discovering new music; after a fan adds a track to their personal playlist, they’ll listen to that artist 41% more; folks in Phoenix buy the most CDs; and Seattle fans buy the most vinyl.

The Fan Study is organized in four chapters: Reach; Engagement; Release; and Merch.

Feel free to wow your math-adverse friends with this one: An artist’s top 5% of fans listen six times more than the rest of their fans.
