Hurray! Check out this blog for Rhapsody subscribers: rhapsody rock school: "from the musical mindes of the people who brought you Rhapsody"--I'm guessing this is some of the old Listen.com bunch.
There are about 15 contributors, and they post news as well as share playlists. Scroll down and there's a playlist of 39 of the Rolling Stone 50 list.
Enjoy!
