When i download a song, the file has no artwork, so i go into itunes do some research on the song find the correct name for it etc and then find the artwork and the picture shows correctly. however when i then go to the file in the music folder the icon does not change to the picture of the artwork? WHY? its annoying. see attached Macklemore & Ryan Lewis - Can't Hold Us (Ft. Ray Dalton) has artwork in itunes but not in the folder where its located.
