Microsoft has been busy streamlining SkyDrive to make the most of our time in the cloud, but it hasn't yet cut out the middleman for audio playback; if a song wasn't obtained through a channel like Xbox Music, it won't play online in Microsoft's universe. LiveSide has made some code discoveries suggesting the storage service could at least partly remedy the problem with a web-based music player. We don't know much of how it would work, although the presence of interface elements hints that Microsoft is at least committed to development. The real dilemma is an absence of clues as to when (and if) playback will ever go live -- and there's nothing that would reveal whether or not SkyDrive is the heart of an upcoming option to upload personal tracks for Xbox Music streaming. If the music player mentions reflect more than just experimentation, however, the Redmond team may soon have a more direct answer to the likes of Amazon Cloud Player or Google Music.
