A couple years ago, I found audioscrobbler and I saw the future of music discovery.

Since then, I’ve seen Mog, iLike, and others copy the idea and build interesting music discovery services around the simple idea of recording your music listens and using that data to power music services that are customized to your tastes.

I am interested in creating a list of all the various services that are out there that use some version of music scrobbling technology. Please feel free to add any and all such services in the comments.
