When I updated my music library, I actually had to remove all my ‘discnumber’ metatags for a multi-disc to only show as a single album but the information when I go to the album it shows the proper songs on the right disc numbers… Now mind you, all multi disc albums I own are very popular so I would expect the information to be correct…
To be honest, if I had to put all of the tag information myself, and make sure its 100% right, that would take away the point of having cloud information at all. Plex used to do a good job of matching my content - in the right folder layout, and with pretty good tags - to show albums well. These albums used to be fine. Something has broken in Plex or its metadata provider.
I’ve tried using the tick box “Prefer Local Metadata” and it doesnt make any difference.
Disc numbers are very important on multi-disc sets. In my experience, if they aren’t there, Plex can be very unpredictable in how it catalogs the set. I’ve seen Plex create Disc 1 with 1 track, Disc 2 with 12 tracks, and Disc 3 with 30, and there were only two discs in the set. And this was 2 or 3 years ago, before the recent changes. Adding the disc numbers to the metadata fixed it immediately.
Something else I noticed: In Musicbrainz, the 3-disc version of this set is entitled “Man on the Rocks (super deluxe edition),” and the “Man on the Rocks (deluxe edition)” is a 2-disc set. I don’t know if this is important, but you might try making the title in your tags match what MB has exactly. I know Plex is picky about the artist name. Maybe it is about this too.
The recent changes to Plex have made some great improvements, like eliminating the Plex Dance. But it also seems to be much more sensitive and unpredictable if tags aren’t precise. Whether that was necessary to fix other issues, I don’t know, but it appears to be the case.
