iTunes artwork has disappeared
Loads of my album artwork has disappeared from iTunes. It seems like it is almost (but not entirely) artwork which iTunes had found by itself, as most can be re-downloaded by using Get Album Artwork.
Any idea how I can resolve this other than going through the albums one by one? If I select all my albums it basically locks up my laptop forever while it tries to find artwork for albums I already have.
Thanks
