Album art missing... but its there.

Please help someone. have had this fifth gen ipod touch since the day it came out. everything was alright up until a few weeks ago. i have about 40GB of music on here. about 3 or 4 weeks ago i was at the mall, decided i wanted to listen to some music and all of it was gone. i thought that was strange, i dont sync it too often but i had it hooked to the computer a day before this incident happened. anyway, i didnt make that big of a deal out of it. I went home, synced all of the same music back, just normally as the next person. i used my ipod a little after it finished and discovered all my album art was gone. i was ******, because i work extremely hard to make sure every single song on every album has its art. later i checked my computer to make sure it was all there.... it was. i clicked the sync button to see if that would work.
Now heres the weird part.... the album art only shows up in coverflow and when on the now playing screen. but not anywhere else. its blank when i scroll the the album lists of artists and its really upseting me. i would love to get in contact with apple but im not sure how.dy

i doubt anybody besides me is having this problem, but if you so happen, PLEASE help me out. i would be most greatful
