I've really been digging this lately.
You make a free account, you get some points from logging in/listening to the unbumped music on the side (the rack).
You bump songs you like and when others bump those songs you get points.
It is largely new, unsigned music, but they've been getting some big bands 'testing' their new songs lately.
Just fun and it runs fine behind other programs.
My name on there is Melestav if you want to check my profile.
Anyone have any other neat new music related programs?
