Sync music between your phone and PC
Do you have content on your PC that you want to listen to or watch on your phone? Use the Zune PC app to sync music and videos between your phone and PC, and to manage your media collection.
Download the latest version of the Zune PC app from www.zune.net/ . You cannot sync DRM-protected music with Zune.
Connect your phone to a compatible computer with a USB cable.
On your PC, open Zune. For more info, see the Zune help.
You can also use Zune to make playlists of your favourite music, and copy them to your phone.
