Microsoft and Sony are teaming up to help power Xbox Music. Although the music streaming service launched in October last year alongside Windows 8, Gracenote, a division of Sony, is announcing today that it now powers the Xbox Music matching feature. Xbox Music users can simply play a locally stored song in Windows 8, obtained from ripped CDs, iTunes, or just regular MP3s, and Xbox Music will automatically detect the song, tag it, and make it available in the cloud for other devices to stream it. Xbox Music has supported music matching since shortly after its launch, but Gracenote’s integration should improve the process and allow users to edit songs and fill-in missing album cover art and other vital information.
