Thank you, my apologies for the hallucinated entitlement. I read your post shortly after I posted here. One other thing, what's the documented behavior if Apple Music is in the foreground but not playing anything, and my app attempts to do player.play()? I have experienced a queue success but playback failure on MacOS (so using ApplicationMusicPlayer), only if the user has the system's Apple Music up. What's the documented behavior if the user has something actively playing on the system music player?
