I have an album titled "Gypsy Soul", genre "Flamenco" (Narada label - Nuevo Flamenco collection, probably out of print, but worth looking for). The album art is correct, and all tracks, except one, have the album art, which is correct. The track "Mediterranean Sundance", Artist "Al Di Meola" defaults to the original album's artwork, not the "Gypsy Soul" album it's in. The album and genre tags are right.
As an experiment, I changed the artist to "Armik" and the title to something in Spanish. Same file, different artist, track name, and got the right artwork.
Change back to the right artist and title and... Wrong artwork.
Why and how do I fix it?
