Hi, JoeKun, Could you let us know why we cannot use currentPlaybackRate for Apple Music contents? Is there any agreement available? In my App, currentPlaybackRate is useful to adjust playing speed based on expected tempo. I strongly expect to be reverted this fix. Expect that 3rd party app also can use currentPlaybackRate for Apple Music contents.

I would like to have a property of lossless in MPMediaItem or somewhere to be enabling or disabling lossless. I'm not sure a reason why but sometimes music which supported lossless will be stopped suddenly (usually, within 15 seconds) when playing on my music player (applicationMusicPlayer). Still under investigating...
