iPod touch Album/Movie/Podcast Art Gets Randomly Shuffled

Sometimes, when I put a new album, movie, or podcast on my iPod Touch the device automatically assigns it artwork from another file. For example, one of my music videos has the movie artwork for "Up" and all of my Radiohead albums were assigned an album cover from John Coltrane. I'd manually fix all of them, but I have 32 GB of movies, music, and podcasts to file through. Very annoying, and seems like something that could have been easily addressed.

Hmm. It doesn't seem to be such a nuisance that it should require a restore. I think iTunes just assigns album artwork that has keywords that match other albums. The "find artwork" option seems to be the problem, and it baffles me that they should allow a program to guess what something is when it isn't sure. However, I can't see any scenario where "Up" artwork would be assigned to a Bob Dylan music video from his new Christmas Album. Ha!
