theory exam car

i just passed :D !




and now the reason why i made this journal is another itunes question.. :P
i have itunes @ my pc and my laptop..
on my pc i have all my music / videos and on my laptop i have a few songs i would like to add on my ipod.
can i add these songs into the library and update ipod?
cause the other songs that are allready on my ipod but not on the laptop so i dont know if itunes removes them from my ipod because i dont have them in my library..
kthxbye
