PLEX is messing up my Music library organisation

Make the configuration changes detailed in this post: Best way to add album, singles & ep to a Premium Music Library - #8 by OttoKerner

Verify that your music is organised in this folder structure

/Music
   /Artist Name
      /Album Title
         01. Track Artist - Track Title.flac
         02. Track Artist - Track Title.flac

Verify the embedded meta tags of your files:

  1. The content of the meta tags Album Artist and Album Title must be identical in every track of a given album. Which means that ‘Disc 1’ etc don’t belong into the Album Title meta tag. There is a separate meta tag for the disc number.
  2. If you have different Track Artists within the same album, the ‘Album Artist’ meta tag must exist and must contain the same content for all tracks of the album.
  3. If the meta tags Track No. and/or Disc No. are existing, the must exist in all tracks of one album.

After you changed file names, folder names, or meta tags, you must perform the Plex Dance
