Wow, now I'm a member. This is BRILLIANT. You listen to your neighbour radio, and it streams things you might like which you can then approve or deny ("love" or "ban") and the ones you love go onto your loved song radio, which you can build uyp indefinitely into the ultimate online mixtape of songs you love, to be listened to anywhere you have the internet.

approve - islands - twinkly loveliness
ban - squarepusher - disgusting post-jazz TOSS
approve - syd barrett - octopus - HOW did it know i love this one?
Xiu Xiu - I luv the valley - ditto
