Pandora is something thats seems worth a further look at. Below is their description of what it is all about.

Can you help me discover more music that I’ll like?

Those questions often evolved into great conversations. Each friend told us their favorite artists and songs, explored the music we suggested, gave us feedback, and we in turn made new suggestions. Everybody started joking that we were now their personal DJs.

We created Pandora so that we can have that same kind of conversation with you.

I’ve been playing around with it and so far it seem pretty neat. They give a 10 hour free trial to anyone who wants to play with it. So far it is very interesting how this thing decides what to play for you. You have the ability to tell it if you like what it plays for you and it fine tunes what it gives you based on your input. Head over here to listen to my little test station. Keep in mind after the first 10 hours you have to pay them 36 bucks a year.
