I can't find anything on this anywhere. I am putting in the PE forum because this problem only started occuring after installing PE. It seems that most times (but not every time) that my phone reboots all the songs that google music had pinned and downloaded need to be re-downloaded. I've tried wiping cache for google music & even uninstalling the app, but this problem continues to occur. Anyone else experience something similar, or have any suggestions on what could resolve this problem?
