I just added 3 new albums to my Music library. In one album, the TPUB tag is populated with “Putumayo World Music.” Another is tagged “GRP Records.”
When Plex imported these albums, the Record Labels were recorded as “Putumayo” and “GRP / MCA.” As you can see, these tags do not match the TPUB tags.
LMA is tops for every agent, and “Prefer embedded tags” is enabled, so Plex should be using the TPUB tags.
