Question

when i added songs from a dif. computer into my ipod my other songs were erased, why? And what do i do?

Answer 1

Because, whenever you plug an Ipod into a computer with iTunes, you're ipod will autmatically update itself to the songs which that computer has, and erase the songs that it has on it already.

Answer 2

Your Ipod is currently set to mirror the library of the connected computer (auto sync) you want manuel sync http://www.apple.com/support/ipod/tutorial/ip_gettingstarted_t3.html
