Artwork for music added to iTunes library
Sometimes when I add music to iTunes, converted from vinyl album or cassette, random artwork in the form of a document appears (e.g. a recipe from BBC Food). I have tried deleting the artwork and replacing it with appropriate album artwork from the internet but nothing changes and the original document image remains.
Has anyone had a similar problem and know of a solution a solution?
