Smart playlists broken in

One of the annoyances I’ve found in switching from Mojave to Big Sur (skipping Catalina) is that smart playlists are broken in

  1. Create a smart playlist (containing songs from several albums)
  2. Switch to Songs view in natural sorted order
  3. Reorder some of the songs
  4. Quit and restart it
  5. Expected behaviour: the playlist retains its natural order
  6. Actual behaviour: the playlist has been resorted in order of Artists and Albums

It’s been like this in every version of that Apple have released since I upgraded to Big Sur. I reported it in Apple’s “Feedback Assistant” (their successor to Bug Reporter / Radar) a while back.
