After transferring my iTunes library from an old desktop to a new laptop, my iPod Classic (160GB, Last Edition) lists a few artists multiple times and some albums are missing artwork. 95% of my iTunes library is from CD's I've burned. I've noticed a couple of artists showing up multiple times are from iTunes purchases where I've edited the artist (for example, Eric Clapton's Complete Clapton, where I put the artist as Eric Clapton vs. Cream, Derek and the Dominos, etc., on certain songs). My iPod Touch (64GB, 4th Edition) shows everything perfectly, as it is in my iTunes library on my laptop. Any suggestions? Thanks.
