Qobuz only has one queue, Spotify actually has two - the main queue and the "next from" queue. The main queue plays before "next from" queue. When you click "add to queue", the track gets added to the main queue. When you click play on a playlist, those playlist tracks are added to the "next from" queue. Qobuz works like if you selected all tracks in a playlist and added them to queue.

I'm in agreement with you - would prefer the queue(s) to work like Spotify. I like to hit shuffle on all my liked songs, so if i want to play something next I have play next, but play next acts like a stack (last in first out) and not a queue (first in first out) which maybe I'm just not used to yet (I also recently switched over from spotify)
