For some reason, half of my album artwork isn't showing up on my 4G iPod Touch at all. This really irks me because I'm the kind of person puts a lot of effort into making sure that kind of stuff is in order and the fact that it isn't showing up is making me want to pull my hair out right now. I connected it to iTunes and MADE SURE that the artwork was saved to the ID3 tags. I did it twice, actually. I tried restarting it. Did that twice, too. For some reason, it just won't show up. The weird part is, it's not just my songs. It also won't show up for a podcast I've downloaded recently, too. I even went and found the artwork for that, saved it to the ID3 tag and...surprise surprise...it's not showing up either. The only changes that I've made recently are updating the firmware of the iPod to 5.1.1 (9B206) and updating iTunes to version 10.5.1.42. I don't usually update but I did because I thought it would be a quick fix to a minor problem. I ended up with a whole new set of them. Go figure. If anyone has any input/insight/suggestions, I would greatly appreciate it.
Right click on the song and select "Get Info" and then select 'Artwork' tab. Add the artwork. If all else fails re-sync all your music.
