This site is so cool. You just type in an artist/band, and you get a song by that band. Then it will just play music by artists that make the same kind of music. If the program took a wrong turn, you just say: this is crap. So it allways plays the kind of music you like

It really has more music than you can listen to in you entire life I think. This rocks ^__^
