Apple Music is way out of the normal density expected from a quality app. Apple has a phenomenal understanding of UI and they're one of the best - just look at the UI of the settings menu on your iPhone. Everything is cleanly laid out - just the right amount of information density. Apple Music seems like it was designed by someone like Will-I-Am (sorry :-) ) with absolutely zero understanding of basic functional UI principles.
If I were to design UI, I'd design it like how aviation does cockpits. Functional, not "trendy". Everything has a reason - if you can't explain "WHY", you shouldn't be designing UI. Personal taste, subjective opinions, "I kinda like it that way" doesn't work in aviation industry. Please don't take it as I mean Apple to follow the same principles, I am just mentioning the other end of the spectrum in UI design to provide contrast.
