Plex Combining Tracks Under One Album for Artists w/ Multiple Albums

Ah, good.

It’s probably “all,” or at least “most.” Plex did a major overhaul of the music scanner last year. It’s a lot more accurate than the old scanner when tags are exactly as Plex expects them, but the tradeoff is that it’s a lot pickier about the tags being exactly as it expects.
It’s also pickier about the folder structure and filenaming, which seems completely illogical to me, but so it is.

Update: As of build Plex Media Server build1.23.3.4692, Plex is no longer dependent on the folder structure or filenames.

Plex has a lot more to do in this area. I remain hopeful.
