Will an ipod's songs go away if you plug it in to a different computer?

it depends on what kind of iPod it is. I have the little clip-on mini and a bubble pops up on the computer asking me if i want to delete my songs and continue or if i want to take it back out of the unknown computer. the mini's will give you an option first, it's not like all the songs will suddenly disappear. My sisters ipod is the new video kind and it doesn't care what computer it is hooked to. it will download songs from anywhere without deleting anything.
