EDIT: I fixed it. Removed the album and readded it and all is well now 
(Basically, I had a folder in my Video Library that was incorrectly displaying an artwork from an album in my music library (The folder and album were made by the same artist) and the only way it would change to the correct artwork was if I renamed the artist.)
