@youtubemusic Something is wrong in the library section of the app. It is only showing music on my device vs playlists I've created within the app and albums I've added to the library.
That doesn't seem right – try clearing the app's cache and make sure your internet connection is stable. Also, uninstalling and re-installing the app usually does the trick. If all else fails, we'd recommend you send us feedback via our Send feedback tool: http://yt.be/help/feedback
