All the music stored on my iPhone has gone following a backup/erase/restore. All my apps, personal data, photos, videos, contacts etc are back as before, but none of the music has been re-transferred back onto the device. Instead, the Music app just lists all the songs I've purchased from the ITMS (ignoring everything I ripped from CD) and indicates that they're available for streaming. I *never* use streaming, I always store my music on my devices. Has something gone wrong somewhere, or is this expected behaviour for a backup? I manually manage my music, but surely that doesn't apply when restoring a backup? Or does it? Do I need to set iTunes back to "automatically sync" before I run the restore?
