Even though I completely sync my iPhone to iTunes, some artwork and albums are different. For example, I have 'Oh, Inverted World' by The Shins. It shows up on my iPhone under The Shins, but once all Shins albums open, it has Various Artists. Meanwhile, this album doesn't even show up in my iTunes Library. I have a second issue with the artwork in the bottom left corner (Mac, not iPhone), and the coverflow artwork at the top of the screen. I have one album that shows two different artworks in these locations. Is anyone having problems with iTunes artwork?
