I am not holding my breath for this one, but if you get any traction, please let us know.

Thanks for this, but I'm not sure about your syntax (with the underscores) or the ability to access the current player. I know that music.volume = 0.05; works when music is an MusicKit instance. I can get isPlaying from music.player.isPlaying, for example, but I don't think music.player.currentPlayer exists.

Amazing, right? The redheaded bastard of the Apple Music world has a state that I never use. Seriously folks, you should hire me to fix this stuff.
