Not just Apple: Karma, Vibez, and even S35/Forge/Cali etc have completely dedicated volume buttons (though Carbon didn't). I think the thinking was, you never know when a new track's going to start that's hopelessly louder than the previous one, so, whatever part of the UI you're in, you need the "volume down" button to be "volume down".
