Google Play Music iTunes Empty or Blank Playlist Issue Fixed!

Alright, So after a stroke of luck, I've managed to solve the blank playlist issue, at least on my device (2010 Macbook Pro running OSX Mavericks)

The steps are not complicated, there are just a lot of them, also scroll to the bottom to see a short cut that might work before going through all the steps.

The apps I used:

AppCleaner

Can be found here: http://www.freemacsoft.net/appcleaner/

or here: http://download.cnet.com/AppCleaner/3000-2248_4-10867510.html

(watch out for CNET's bloatware, do the custom installation of their downloader and un-click all the add-ons)

So here's what I did:

**Deleted all of my iTunes playlists from Google Play Music using the Web Browser Interface

**Exited out of Google Play Music Manager and used AppCleaner to search for and move all the related files to the trash

(Related files being):

​

MusicManager app located at /Applications/MusicManager.app

​

com.google.musicmanager.plist located at ~/Library/Preferences/com.google.musicmanager.plist

​

MusicManger folder located at ~/Library/Logs/MusicManager

**Note, it might be hard to delete the app if it is still in use for some reason, to delete it use the "Secure Empty Trash" in the finder menu**

***Reboot the Computer***

***Before attempting the following steps involving iTunes files, it is important to know that this will reset your iTunes and all devices linked to it. More information can be found here: http://support.apple.com/kb/ht1451

Go into the iTunes music folder on your computer (iTunes must be closed):

**Take the iTunes Music Library.xml and put it on your desktop, put the iTunes Library.itl in the trash (do not get these confused!)

**Reopen iTunes (all of your playlists will be gone, most of your music will be gone), and import the iTunes Music Library.xml back into iTunes using the Import Playlist Feature

**Let iTunes do its thing, this could take a while depending on how much music you have

***Finally, reinstall Google Play Music manager, select the iTunes music folder (or where ever you keep your music) and Voila! your playlists should sync when google play music finishes uploading your library. Uploading should only take a few hours or less since Music Manager is just verifying songs instead of uploading them.

Possible, Unverified Shortcut:

I realize the above steps are long, but after completing them everything worked again. If I had to guess, the source of the problem lies in one of two spots, the com.google.musicmanager.plist file, or the iTunes Music Library.xml file. If you don't feel up to completing all the steps above, I might suggest:

1.) Uninstall Google Play Music Manager, find and delete the com.google.musicmanager.plist file, then reinstall

2.) Exit out of Google Play Music Manager, complete the iTunes steps listed above, reopen Google Play Music Manger

3.) Try to complete the steps listed by wideasleep1 in the previous post

If you are running a windows computer, the steps should be similar (maybe some files in different locations), but uninstalling shouldn't be as complicated.

Sorry for writing a book, I hope this helps!! :o
