It was earlier this May when we brought you word that Xbox Music could eventually be the recipient of a cloud locker, and here we are with the very real possibility that Xbox Music has already received the ability to support the OneDrive locker, never mind the fact that there has been no official announcement concerning the release date for such a service at the moment. Details posted on Piptell do feature a bunch of references to the OneDrive locker service in text files that currently see action on the Xbox Music site.
Basically, anyone who happens to own a Microsoft account in select regions are able to add music to OneDrive, and to play it back over on Xbox Music. You can also hook up OneDrive with Xbox Music in order to enjoy the playback of your personal music files across your collection of devices. In addition, any music that has been uploaded to OneDrive can be streamed from your collection all the way to the rest of your Xbox Music devices.
Hence, we would not worry too much about the missing release date, since all of the details that have been posted do make it crystal clear that Microsoft is inching closer to a formal launch, and everything does seem to be in place already.
