Of course they can't add this: they're too busy rebuilding the UI so the (I assume) new Art Director can climb the corporate ladder.
It was just constantly frustrating to battle them, so I switched to Tidal, and it's been amazing. The UI is just simple and lets me play music, and nothing has broken in the last year. The only changes have been minor improvements that make it even easier to do the one thing that I want: to play music.
Instead of having a discussion about how it could be improved, maybe we can have one about which alternatives exist and how good they are (tidal, is it?)
EDIT: I tried Tidal, that app has a confusing mess of an interface just like Spotify. Plus they have a "convenient" bug during sign up that may sign up students with more expensive non student accounts.
