MPMusicPlayerController.applicationQueuePlayer opens Music app, which is not the goal.

Using Xcode 14.0 beta on MacOS 12.4

I have a simple app to play items in the Music library. I'm using MPMusicPlayerController.applicationQueuePlayer to play the music. Nowhere in my project do I refer to the systemMusicPlayer, nor do I have any instances of MPMusicPlayerController() alone.

Yet even if I quit the Music app, selecting a new song opens the Music app.

The code I use:

// inside a View
var mainPlayer = MPMusicPlayerController.applicationQueuePlayer

//at the end of the HStack representing a single song
.onTapGesture {
        mainPlayer.setQueue(with: MPMediaItemCollection(items: [song]))
        mainPlayer.prepareToPlay()
        title = song.title ?? "-- No Title --"
        mainPlayer.play()
}
