On November 14th, 2006, MSN Music stopped offering music downloads through the MSN Music store. The Buy buttons that you were used to seeing on the MSN Music album and artist pages have been changed to links that connect you to Zune. MSN will continue to offer support for songs that you have already purchased.
If you bought music from MSN Music, it is yours to keep and enjoy in accordance with the content usage rules. Specifically, you will still be able to:
Use the tracks downloaded from MSN Music on five authorized computers.
Export the tracks for personal use to compatible portable digital players.
Burn tracks and playlists to CD solely for personal, non commercial use.
