Anybody else use last.fm? In case you don't know it records what you listen to through a scrobbler (originally the site was called Audioscrobbler)
It's not 100% accurate since some of my music doesn't have proper tags, and often times it won't register artists correctly if someone is featured in the song.
Regardless my site is here:
