Last.fm

If you want to keep up with what Dwight listens too check out my last.fm page

This site is really cool, I use it because it tracks what I am listening to in iTunes, and compiles a list of my favorite artists and tracks. Then it compares my library to other user's libraries and shows me people with similar listening habits. It also recommends similar artists. The coolest thing it does (and the thing I use the least) is that it gives me a streaming radio station made up of tracks I like and might like.

Very cool if you have a always on internet connection (although I think it will send all the tracks you listened to offline the next time you connect.)
