Apple, Amazon and Google all have playable cloud-music lockers, so it would hardly be a surprise if Microsoft were to follow. The company already has Xbox Music, of course, which has been confirmed to be getting scan-and-match features sometime in 2013.

Its post also has images showing what appears to be a (REALLY ugly) tests for some kind of music player from Microsoft’s internal tests. It’s all very interesting, but also slightly puzzling: with Xbox Music free in its basic tier, why would Microsoft want to encourage people to store music in their SkyDrive accounts to play?
