Give artists on Spotify the option to choose their city (base location, whatever one may call it). Give users a space to browse these locations in Spotify. Thus, a map containing all artist locations. Users can find artists from certainc cities, famous artistic areas, nearby locations, etc.
I think this would contribute to the promotion of local artists and boosting talent discovery on Spotify. Something Spotify is already excelling in with the size and accessibility of its platform. Also, good USP 😉
