New Nexus 10 32GB. Essentially in "factory reset" state, with the exception of connecting to WiFi and setting up my Google account and wallet. Everything works perfectly except for Google Play Music. It responds with "Music temporarily unavailable" when I try to play any of the pre-installed songs. Clearing the app cache doesn't help, nor does uninstalling and reinstalling the app updates. All of the other Google Play apps other than Music work properly. Sound and video are working properly in general (e.g., YouTube app works fine). I have seen many others with this problem across the Internet, so it's apparently something endemic to the device/build. Has anyone encountered it and found a solution? Thanks.
