The new service called "Music Match Downloads" is notable in that it has obtained consistent licensing across record labels (similiar to iTunes Music Store), allowing their users to burn songs as well as transfer songs between players with fewer restrictions. Songs will be offered at $0.99/song or $9.99 "for most albums".

These looser restrictions will apparently be also given to existing services, including BuyMusic.com (and presumably for iTunes for Windows)

MusicMatch plans on offering their service under the Windows Media format. These files are not compatible with the iPod player at this time.
