I figured out how to fix this. Google music api was not loading correctly. It was missing some required dependencies and was not completing installation. I manually pulled the gmusic api from the github repo, ran the install script and watched for errors. I had to add some required python libraries using pip install <x> (and apt-get), several times, until I was able to finish building the app without errors. Once google music api was properly installed, the google music plugin loaded just fine. Everything is working now.
I would recommend that when pushing out newer versions of max2play, you guys make sure that you include all required dependencies for gmusic „out of the box“.
