Spotify in the early days used to be great for this. Their entire catalogue was browsable with fine grained genres. They ruined it and became useless for music discovery.

If Last.fm is still around that may be useful, they are/were great at finding similar artists so you could go to one artists page, click through similar artists a couple of times and find something fresh that you didn't know you liked.

It was also great because you could hook up your music player of choice via plugins to Last.fm and it would do a damn good job of regularly finding your next favourite artist/track on your profile page.

Like most things tech related the music realm only seems to get worse as time goes by.
