Brent sez, "MSN Music is shutting down, in favor of pushing Zune and Real Rhapsody for their 'Buy Now' links. News.com says MSN Music files won't play on Zune or Rhapsody, and there's no upgrade path."
As for those who have bought MSN Music tracks, Microsoft said on its Web site that users will still be able to use their songs, transfer them to compatible music players and burn them to CD.
You were a sucker if you bought MSN Music tracks. You're a masochist if you buy Zune tracks.
