There are two tracks in my Itunes library that seem unable to “hold” artwork. I go to the appropriate window, and add the art and it looks like it’s there. But as soon as I hit “OK,” it seems to disappear, and when the track is played, there’s nothing, and, indeed, the artwork window is black.
That’s not really an issue. The artwork is gone on those two tracks and those two only. I open up the “info” window, and the artwork that I had added just is not there. It’s there for the remaining 5,300 tracks in Itunes.
