I recently realized I haven't actively listened to music for almost a decade. Some life stuff combined with a job I've had for awhile that really exhausts me, and I guess I hit a dead end without realizing it.
Back in the Before Times, the local radio stations played exclusively power trio stuff, and I sort of came to the conclusion that... I didn't like music? Which is obviously dumb, I just had a limited window on things.
Then Pandora happened and life was good. You could throw thumbs up / down at stuff and it would figure out what you liked. It was around this time I figured out that I liked stuff like Thievery Corporation, but since there wasn't any way to export your history, I don't recall many names from that period.
Pandora kept getting worse until I stopped using it. No idea what email I even used at this point. For some reason, probably stubbornness, I never picked up a Spotify account. And so here we are today: I don't listen to music much, and I don't even know what I like.
So like, what do? When I hit up Youtube for some search like "focus music" for getting stuff done, or "viking music" for playing Valheim with friends, I usually enjoy it, but that's a far cry from actually having a taste in things.
I like listening to what artists I like listen to and get into rabbitholes from there.
If you find someone you like, try and see what they say their influences are. When I get into a new genre it's daunting on how to even find new names in there to listen to, depending on how obscure the genre is.
If I hear a cool bass riff or guitar work or whatever instrument in a song, I look up performance/production credits on discogs; and many unnamed people on pop tracks or whatever are session musicians who do a wide variety of stuff and don't usually limit themselves to one genre. And jazz musicians seem to pop up wearing many different hats.
Smaller record labels usually work with narrower genres so that could be useful if you find a band you like and want to expand from there.
