You can also try the following.
Open the CON file in CON Explorer. Extract the DTA. Find the following line
(album_art TRUE)
and change it to FALSE
If the line isn’t present, then add it somewhere near the bottom (but not as the last line in the DTA).
Save it, replace the DTA in the CON with this new one, and try it in game. It *should* default to the game art and not the album art that’s present in the CON file.
