Last.fm

Last.fm is my latest online addiction. If you like Pandora or other internet radio sites you have to check this one out. Last.fm does all kinds of neat things such as keep records of what you're listening to not only in their browser but also on iTunes, Media Player, iPod, etc. Stations are created for you based on what you like and don't like. I also enjoy the interface more than the other radio channels I've used. You'll hopefully see some of the Last.fm features on this site in the near future.
