This is something that I noticed whenever I use a friend's iPod, they're always chaotic
It takes so much time to find a song, some albums or artists are listed twice, and most of the songs are missing the cover art =S.
As for my iPod, I always make sure that all the names are spelled correctly so that the names wouldn't be duplicated, list the tracks in the correct order, and take the trouble to find every single cover art (unless I don't like it, lol)
What about you guys ? Are you crazy about keeping everything perfect like me ?
