Another great new feature included in iOS 16 is the ability to drag and drop to organize songs in Apple’s official Music app, similar to how you can organize the app icons on your Home Screen.

You can also use the drag and drop gesture to add a song to the playback bar at the bottom of the screen. The same operation can be performed from the albums view to drag an entire album into the queue.
Added content is placed at the beginning of the queue.
