this is a cool site that gives you other music that has same sounds of bands you already love. good way to find new music. has tons of indie bands even.
I can't be arsed to register for every little spam post. Useful or not.
allmusic.com gives you the same info...only they pretty much suck, as any other website trying to achieve this...rating gorilla biscuits same as the cure or some shit or whatever....artificial inteligence has no sense of good music
i'd say audioscrobbler was spot on
