Anyone else use Last.fm? It's a website that keeps track of all the music you listen to and you can see charts and stuff that will show how many times you've listened to each artist or each song over time and stuff. I think it's pretty cool.

Here's my page as an example. My play count is kind of low since I just redid my Itunes in April so can only go off everything since then, otherwise it uploads all your previous plays as well. If you sign up add me.
