I don’t mind these genres but looking at my personal collection I have 400 gigs of rock, 500 gigs of rap, and 800 gigs of jazz. None of these three genres ever appear for me on Spotify. Spotify is by far the worse way for me to discover music because it’ll never show me something new or different; just the same song several dozen times.
The best way to find music is talking to people. Before what.cd shut down they had collages that I’d make heavy use of, basically lists of songs and artists for a variety of genres or feelings. One I’d heavy contribute to was jazzy hip hop. This one genre would encapsulate 30-60 artists which I’m sure that Spotify would put in separate worlds.
There has never been a “recommendation” service that I have found more useful than talking to someone.
