Now, my iPod Touch is organized like this: I only have two major playlists: my purchased songs from iTunes, and the purchased songs from my iPod. Anyway, I thought if I can remove a few songs from my iTunes-purchased songs for cleanliness sakes. However, when I removed a few and tried to sync up my Ipod, I got a message that it won't sync because my iPod is not there. After putting the songs back, I got my iPod to sync properly, but it won't display the album covers of a few of my songs. How did this happen, and more importantly, how can I get them back?
