Server Version#: 1.27.0.5849
Plex Music agent/scanner is no longer honoring embedded sort tags. I have all of my music tagged with embedded tags (90% .flac; 10% .mp3) and at a minimum all include track name, album name, artist, album artist, artist sort and album artist sort.
I have my music library set to “Prefer local metadata”, and previously Plex would properly import the “album artist sort” tag from my files to the “sort artist” data field in Plex. I recently performed “refresh metadata” on my library because with the server update the date error (showing albums a year early than tagged) was fixed.
Unfortunately, with a refresh of the metadata, Plex updated all the data in the “sort artist” field to a format completely different than the embedded tags. All solo artists in my library have “album artist sort” tags set to lastname, firstname. However, Plex changed all the data in the “sort artist” field to firstname lastname.
I performed a plex dance on my music libarary, and have been adding artists back to the library. In doing so, the Plex Music agent ignores the “album artist sort” tag in the files I add back, and is populating the “sort artist” data field with firstname lastname.
