A different thing but related: why is Spotify's queue a queue and not a deque? Late Google Play Music had a deque, Tidal has a deque. I often create a long queue of songs and then remember to add a few more to the beginning. With Spotify I have to add them to the end and then manually scroll them all the way to the top. Actually that's one of two reasons why I chose Tidal and not Spotify when GPM died (the other one is that they pay more to the artists).
