The old Nether music seems to never play, but the changelog never said that the old music was removed. This can also cause no music to play at all in the warped forest.

No, this has nothing to do with MC-177795. If you look at the sounds.json, so_below and chrysopoeia have a weight of seven, and rubedo has a weight of six whereas the other four tracks have a weight of one, so it's intentional that the other tracks have a lower chance to play.
Cannot reproduce. So far in the last two hours it also played Warmth, Ballad of the Cats, Dead Voxel and Concrete Halls. This was in the Crimson Forest in case that matters.
