Missing Artist Label

[TheDreadPirate]

You have a few options. Manually adding metadata tags in your music. I think you can still use MusicBrainz Picard to do this. Winamp and other music players can do this. You could also create a MusicBrainz entry for this band/album. I had to do that when an obscure guitarist I listen to released a new album.

Jellyfin is pretty reliant on metadata tags being populated.
