Since Apple has resolutely decided that the Music app on macOS will remain permanently buggy, but the Music app on the iPhone works as it's supposed to, then it's possible Apple has deprecated the macOS version of Music and is planning on replacing it with the iOS version at some point, once more people have Macs with M-series processors capable of running iOS apps natively. This may be another instance of Apple's typical cutthroat policy of "conserving employee resources" by deprecating or even entirely dropping support for things that they plan to replace at some point, even if that process takes years.
Music app goes where Apple clearly wants.
It’s a front app for Apple Music subscribers, and that’s all.
I’m using a third part player for
MY music, and I love Apple Music also, as a subscriber (a few glitches, but it’s mostly responsive, and works beautifully at synchronization in all your Apple devices).
I guessed years ago Apple’s intention, when trying to have own music & Apple subscription at same time started to be a nightmare. Even the acceptable behavior of iPhone Music app is
intended, because it’s needed for Carplay, Airpods … showing off! Music will keep the ability to play own music just as testimonial aid to sell the “ecosystem“.
I think it’s time to stop whining and start searching for a good player and library manager if you want to use your own big music collection. That’s all; no solution, no hope for Music app to do what a lot of people seem to need, as I read this forum thread.
(IMHO)
