Blank titles in Plexamp, Plex Library has title, edit page does not

The library settings are good. From what you showed me, fix the naming, fix the tags, and plex dance the artist. It’s reasonable to dance an album instead of a whole artist, but I wouldn’t.

This is the official style:

Music\ArtistName\AlbumName\TrackNumber - TrackName.ext

Yours below has the wrong AlbumName

F:\PlexMusic\Corey Kent\Corey Kent - '21\01 - Gold.flac

The one below is missing the AlbumName, TrackNumber is missing, TrackName includes artist.

F:\PlexMusic\Hardy\HARDY - JACK.flac

Same situation as above.

F:\PlexMusic\Tate McRae\Tate McRae - uh oh.flac

So getting the naming right is half the battle, but it’s very common to use Musicbrainz Picard to fix your tags. It’s not necessary, but it will definitely help.

Good luck!
