I use Jellyfin for my music collection, and sometimes the album artist and artist fields for the same artist will be populated slightly differently. For instance, I have one case where there are three different ways using &, ‘and’ and +. I have removed these from my library, updating them with manually with MusicBrainz Picard to use the same spelling, and reuploaded them to my server. However, it uses the old metadata still.
Is there a way to efficiently reset metadata for only certain albums so that these three instances are merged and I can access all three albums from the same album artist?
EDIT: So I managed to get this working now. What worked in the end (unsure if all steps are necessary) was to remove all the files from the server, run a rescan, delete all the albums (they would still be in Jellyfin with a blurred album cover), rescan again, and now the artists would be gone. When I added the albums again, the new metadata would be used.
The server certainly should have picked up the change in metadata but I can’t help you with why it didn’t.
I can suggest that you edit the metadata in Jellyfin rather than using external tools and moving items in and out of the library. Just click the three-dot menu for a track or album and choose “Edit metadata”. If it doesn’t pick up changes made from Jellyfin then something is very wrong.
Hm, the only metadata I can see on the album level is the MusicBrainz IDs. That could explain why it is behaving this way, because MusicBrainz is the reason they are different to begin with, and I’ve had to force the change. I could change on the song level, and that was indeed the old values. However, changing these also did nothing.
All the three different artist versions have them same MusicBrainz artist ID. I tried to change these now into all using &, and it does change it, but now I have three identical entries instead. Trying to select them all and click “Group versions”, it just spins and nothing happens.
