I have had my N7 since last Thursday, but finally decided to listen to some albums on Google Music tonight. I fired up the app and it wouldn't sync with google play to download my music info. Nothing was working including a reboot. I decided to uninstall the latest update. Fired up the app again and it automatically sync'd my music. I then reinstalled the update and everything still works fine. Not sure what the deal was, but thought I would pass this along in case someone had the same issue.
