Umm… You could maybe try to use local (file) metadata as a priority over online databases. If you don’t do that, it tries to discover the album based on the folder name (and files within), then pulls the metadata for that from MusicBrainz (similar to how it gets metadata for movies and shows). Plex ignores all other file metadata at this point. So you prioritize local metadata FIRST, and it ought to pull in the data from your file itself first. I do not know if that works for album art.
If you do try this, be sure to Plex Dance your files.
This is where you set local metadata first:
Maybe look at the next item. I think that this option is already enabled (since your album pulled online art AND file art), but make sure its set to both (for your files that may have no art).
