Just heard of this website from a friend.

Pandora by the Music Genome Project.

Basically you enter some songs/artists that you like, and the site will analyse the music you choose and play songs with the same characteristics - ie., it plays what it thinks you would like. Just add more songs/artists to refine the process. Have just started to try it out, so I can't say how good/accurate it is, but the concept is interesting, the music quality is good, and the user interface is simple.

Try it! I know some of my friends will just love this.
