I cant put my itunes music in my ipod! please help!?

ok my dad just formated my pc and i downloaded the new itunes 9.0.1.8, then i tried to transffer my music from itunes to my itouch! all it says is *there is not enough room on my ipod to copy all the requested files. itunes will copy as many files as possible.* please help!
btw i have 20+ spare mb in my ipod
i try to put less than 3 mb songs just only music not anything else.

that just means your iPod is out of memory. You cant do anything about it (unless you want to buy one with more memory, which i doubt you will want to do)
