My friend just sent me a link to pandora.com
, created by the music genome project. The general idea is you plug in a song you already like, and the program creates a radio play list for you. The program can *learn* too. If you don't like a song you tell it so, and the program adjusts the selections accordingly.
Really, really fun. I didn't have such great luck with my first radio station, but I have been listening happily to my second for about an hour now. Also great for exploring new genres. Try it, you'll like it!
