Music adds unwanted songs when selecting track

I'm using Music, when I select to play an album the album gets queued, and nothing else does. I like this. Play what I tell you to play!

(in this screenshot, I pressed the play icon on the album cover)

However, if I click a song - like track 1 - then a bunch of other stuff gets added. I don't want this. How do I turn it off?

Autoplay and Mix are off
