BIG PROBLEM ON MY iPOD TOUCH!!!!

[uzair_rock]

Today as I connected my iTouch to my laptop and it started syncing with itunes. what i found on itunes in main page of my itouch, where all the specification of songs, videos, pics and application is shown, i found its not showing music there. instead of that it is showing a 3.7gb covered by "other" which is supposed to be my songs.
When i checked on my iTouch all my songs are gone now..... and when in my itouch i went to setting-general-about, it says songs 0.

This means that the 3.7gb of songs are there somewhere but they are showing in itunes as "others"..

Please help me ....its urgent!!

Here is a screen shot from itunes:
