I have a folder named: Music/Beach Boys/…
In the Beach Boys folder there are 11 songs.
On the Plex home screen, I see 2 posters labelled Beach Boys.
One of them has all of the songs, the other has 4 songs, that are duplicates to the one in the first folder. When I check info for both posters, they show that all the files are in the same folder.
Hope this makes sense. Why would there be 2 posters representing the one Beach Boys folder?
Wrong embedded meta tags.
Make sure that all songs have an embedded “Album Artist” meta tag and that it has 100% identical content in all songs.
Also, Plex doesn’t scan songs. It scans albums.
If your files and your folder structure provide no clues about the album, Plex starts guessing. You probably don’t want that.
