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?
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.
It is what I have tried, but Jellyfin still does not want to recognize the new metadata. :/
