http://windows.microsoft.com/en-us/w...m-cd=windows-7 You have it installed already.
The problem I have is that the usb won't play drm files. It will bluetooth from any source drm or not.
You can go wild and convert every file to flac and try it or even go to flac and back to mp3 if you want to strip the drm.
Tell them to just put it on the phone and use the media to play and select even on voice command.
