I have a Google Music plugin 99% completed that operates via the open source GMusicProxy. I have almost everything working except adding to Favourites and Playlists. The plugin utility generates the method addToFavourites, but I’ve had some trouble getting it working with various calls. I don’t see this method implemented in other plugins and the PlaylistManager appears to have custom handling for other plugins. Add to queue works perfectly.
Does anyone have a working example or some feedback they could provide? I’d like to get a pull request up soon.
Appreciate any help.
