Rhadioly

Rhadioly is a free Adobe Air app that reads your iTunes XML file and turns your playlists into radio-like stations. What that means is when you click on a station you essentially tune in to the station at whatever point it's playing. In this way, you don't have to listen to every song from beginning to end. If you don't know what you want to listen to, scan through your stations until you find something you like.
