This popped up over on the dark side so I thought i'd bring it into the light over here. www.yes.com is a site were you can lookup playlists from most radio stations. It does miss a few but is generally pretty accurate. Another great feature is that once you highlight a song, on the right will be a window containing a youtube video if there is one(some are homemade hacks), and in the song list are links for purchase from itunes and amazon. Check it out, it's pretty cool.

Damn cool! Thanks!
