Hi all, I'm using Itunes Match and have had mixed success with it. I'm also using Google Music as a backup service. Every so often songs I've downloaded from Itunes (songs that were matched, but ripped long ago from my cds) have DRM and can't be uploaded to Google Music. It's happened with a Zeppelin song, a Jayhawks song and an Ella Fitzgerald song. The rest of the songs from these albums were fine, DRM free, and uploaded to Google Music. I've deleted the DRM songs from icloud and tried to rematch them, but I get prompted to enter my username/pw to authorize the computer, everytime I play/access the song. I.e., I cannot play these songs locally, even though I have the files. Any ideas?
