My favourite example of Spotify being shit is:

I want to play an album, so I go to it and press play. Then a bit later I want to queue a second album after the first one is done. How do I do that? As far as I can tell the answer is to go fuck myself. I have start a new queue or playlist with both albums in it.

That's apart from all the basic software quality stuff like randomly restarting the queue.

Edit: so now I use finamp with jellyfin, which I can actually fix when it does something I hate.
