iOS Music Controls exercise

Super quick exercise I did wanting to explore an alternative way to display music controls on iOS. My main thought with separating the controls from the Now Playing card was to put them in easier reach of the thumb, especially for the larger phones. The Now Playing card would scroll with notification cards as you scroll, maybe the music controls would retract as you scroll through notifications as well.

Thoughts / feedback? Would this be a good idea to at least explore ways to implement, or are the controls on larger iPhones already very easily in reach as it is?
