Pandora Radio - Listen to Free Internet Radio, Find New Music
Does anyone else use this site?
It's a real cool site where you enter in a band or song you like, and it creates a "radio station" that plays songs similar to that bands style. If you like a song, you can bookmark it. This site has introduced me to sooo many new bands, and also brought up some older songs that I completely forgot about. Its great for finding new music to download with the zune pass.
And its totally free, with no catches.
