I have been enjoying a site called Pandora for a while now at work. They call it the music genome project. Basically, you just type in a few songs/artists/albums that you enjoy, and it creates a music station based on the music you requested. It plays other music that is the same style of the music you initially put in, so listening to the station is a good way to find new, good music, which is sometimes a difficult thing to do.

If you don't like a song that it chooses, you can just click the 'thumbs down,' and it goes to the next song. You can register for free, and then you can just log in anytime you want to hear the stations you create. I created one for myself to listen to when I am working, and one for the kids to listen to when they come into my office. Well, my old office...

I enjoy it... and think you should try it too.
