I recently had to reinstall everything on my HP laptop after a repair. I'm running Windows 7 Home 64-bit. I had backed up all my music to a DVD and cut and pasted it back into the MyMusic folder as before. But when I opened WMP, some of the artwork wasn't showing up, showing a black album cover instead. If that wasn't bad enough, it also started changing the album art in MyMusic to match. I've always used WMP without problems, but I don't understand what's going on here.
