I use Spotify and have great luck there.

Playlists: Discover Weekly tends to result in ~3-5 (new to me) musicians/week that I hadn't heard of that I would actually listen to. That's a pretty high ratio IMO.

Release Radar tends to result in ~1 (new to me)/week. Granted, it's supposedly mostly ones I listen to, but still has several I've never heard of.

Daily Mix 1-6 are a mixed bag and sometimes result in something new, but mostly just things I like (and may have forgotten about too).

Discover Weekly was rather boring for me. It was about 6 weeks before I heard a song I hadn't heard before and only one musician I hadn't heard before in the 3 months I used it.

I had much better success with Pandora when I tried it, but it still wasn't exactly deep cuts.

Maybe that's just because I'm too young, but most of my music discovery since I was 16 maybe was done through spotify, so spotify knows pretty much exactly what music I know and what music I don't know.
