Pandora - Musical Genome Project

Looks like the Musical Genome Project actually has been productized now. I remember hearing about them a couple years ago, and thinking that it sounded like a extremely labor intensive project with unclear goals. But Pandora which is derived from the MGP looks like a solid product. You create a station with your favorite artists, and it streams music from other artists/songs that contain the same musical characteristics. It is great because I like listening to music of a certain "mood", and there is no easy way on my ipod to do that. Would be a great acquisition for Yahoo! Media Group - imagine it integrated with the Yahoo! Jukebox.
