iOSX for iPad 12" - minimized Music Player

A sample of a "minimized Music Player" POP, for quick access to the album playing at the time. By pinching-out you can open the full Music App (I want to make its gif but I don't know how).
Please keep in mind that if the buttons are a bit small it's because it's designed for 12-inch screens and upper.
Tell me your opinions, I'll use/need them :)
I improved my previous work by @Intrepid Pursuits 's idea :)
