I cannot seem to find the option "add album to library".. you said something about being "all access" member... is this what you're talking about?

Adding to Kodi library is not possible yet. I have not discovered a way to Kodi recognize the metadata in the exported tracks.

That feature, available in the album context menu, is related to adding an album from All Access Google library to your personal account library. This way it will be listed in the 'My library' albums inside the addon.

I'm using an addon for music videos. It searches for videos on various online sources including the local music video database. In other words the local library was integrated into the addon. If adding music from google music to the local library does not work, maybe the other way round works, i.e. integrating the local library into the addon? The tricky part is that a filter has to be build in that prevents duplicates from google music and the local library as best possible.
