I’ve almost entirely given up on managing music. Just done with it. I listen to soma.fm and radioparadise.com .. I read one music magazine and listen to some of the music recommendations from there, but following any of it, over time, is a lost cause for me. I was just remarking to someone how music apps are the least interesting, personal, and innovative of all the things I live with. Examples: we still can’t manage…
Youtube Music is quite good for what you're describing.
Youtube music thinks "videogame music" is a genre and lumps them all together, if you make the mistake of including even one song from a game OST any recommendations go out the window.
For example, a "chill" mix with videogame music in it will happily start including Doom Eternal tracks because "they're the same thing, right?"
