peter The function does exactly what it is supposed to do: Moving the next (or current) selected song up or down. The new selection will stay in focus. How else could you see where you are when selection moves out of the visible screen?
Yes, but it has a jerking/flash every time you select the next song , can’t you see it?
Play a song then use the selection buttons , you will notice a very quick flash of the NEXT colour that appears above and below the actual NEXT selection line depending which way you move , this flash is very annoying and should not be happening.
It’s not as bad on my new iPhone 16 pro max but is very noticeable on my iPad Pro, I haven’t tested it on my Mac Studio.
