Here at diTii, yesterday, we reported that Microsoft has released build 7712 of Windows Phone "Mango" to developers which among many other changes has one particular new feature that brings the ability to playback music files from SkyDrive.
As seen in the video embedded belwo, clicking on a MP3 file stored on SkyDrive within the Office hub will bring you to the mobile web version of SkyDrive within Internet Explorer Mobile. When you tap on the MP3 file on there, the Zune music player will then playback the file.
This obviously isn't the optimal way of actually streaming music from SkyDrive, but at least playback is now supported. We certainly hope Microsoft further refines this feature, and possibly integrate this within the Music+Video hub.
