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.
I had this exact same issue and many other odd things. The best advice I can give that worked for me was to one by one take each album off my server pass it through music brains (this looks for and edits metadata) and then place it back into Jellyfin.
It was well worth it in the end. I couldn’t get Jellyfins metadata to work reliably for me, but this was the only issue I have had and the good Jellyfin provides once you have it ‘cleaned’ up is fantastic.
I would start using lidarr instead. Uses musicbrainz as well and can do the library management as well. Imo better than something like picard.
I only used picard in the beginning to fix my unsorted library and prepare for import in lidarr.
It is what I have tried, but Jellyfin still does not want to recognize the new metadata. :/
Did you try also deleting all of the old metadata, to try to get it back to a clean slate
