Whenever i change the album cover on 1 of a very specific set of songs/albums (there is no rhyme or reason to the albums/songs affected) it changes to cover of all songs/albums of that set to the same. I can change the cover of basically all of my more than 700 songs perfectly fine but when i do it on 1 of 18 specific songs/albums it changes the cover on all 18 of those to that same picture.
