Just to pile on the terrible Apple Music UI — it's so unnatural and baffling to me. One example that really takes the cake is that there is no ability to set a sleep timer in the app. After having to google it, the only way I've found is to set a timer in the Clock app and change its ringtone to be an "action" of stopping all playing audio. WHY???
Well, that's Apple and iOS for you in a nutshell. I found out about it the hard way as well. I have mixed feelings about Apple's products and design, but that may be one of the most stupid things I know of.
