I've been getting into a music discovery site:
http://www.thesixtyone.com/KaklickMartin/ The tagline there is something like:
If Guitar hero is about shredding, thesixtyone is about A&R.
You can be an Artist or a Listener - or have 2 accounts, 1 of each.
it's kind of a "game" since listeners get points to "bump" songs with, and one way is by bumping early on songs others end up bumping.
