Yeah, that's basically what it does. What's great is that unlike with Pandora and Last.fm, you can play any song you want, at any time. You don't have to wait for it to show up in a rotation or on an artist/genre channel. The Grooveshark site now has a radio feature which is pretty close to Last.fm in that it continues to play songs that it thinks you'll like based on your listening habits. I'd love for that to get incorporated into nanGroove as well.
