> trying to find music that I like to listen to As mentioned, my problem, as a listener, is discovery, which bandcamp doesn't address.
I’m afraid if bandcamp doesn’t address discovery and SoundCloud doesn’t either then you’re referring to the “shuffle-radio” where you discover new music without doing anything? This is how Brooks Jefferson got to 60m listens in the first place. “Sounds like Garth Brooks!” Because it’s his songs sang by a wedding singer.
No, recommendation systems, like Spotify uses, uses crowdsourcing and song analysis to drive the "radio". You can make "song radio" that has the same style/feeling as a song, artist, or genre.
