The group radio, as far as I understand, it's just similar artists that everyone in the group listens to. So far I've been getting a lot of RHCP, Jack Johnson, and even Lily Allen from the JBB member radio.
If you want recommendations, you'd probably want to go into Last.fm and either listen to your neighbor radio, or go from tune in, instead of tag go under artist, and look for Jimi Hendrix or Led Zeppelin, or any other artist/band you like.
