Legal music's next step?

Watch out iTunes and Yahoo Music Unlimited, here comes MSN's music subscription service. "The tentative features of the new service - which is still under development - include advanced community aspects and playlist-sharing," CNET reports. But here's where MSN will really up the ante: It wants subscribers to be able to play any song purchased at iTunes on music players other than the iPod, what a lot of digital music fans have been waiting for. To that end, MSN is seeking rights from record companies to create a Microsoft-formatted version of any song people can find at iTunes.
