This has been happening a lot and is pissing me off. Let's say I have an album I bought from iTunes on my iPod touch. After about a month of it working as it should, the album art just disappears. The album art is instead just all black. On iTunes, the album art shows up just fine, but not on my iPod touch. Considering that Cover Flow is kind of the big, cool feature on the iPod touch, having it not work properly is frustrating. Is there anything I can do to fix it? Changing the album art doesn't work.
