This ipod manage software can transfer the files from ipod to computer, ipod to iTunes, and iPod to iPod:
When the songs were erased from your Ipod, you can never get it back, maybe you have plugged in your iPod to other PC/laptop that has itunes. You should connect your iPod only to the PC where you have installed your own itunes.
You can do it on iTunes from your PC
if you mean like you bought songs on your iPod and they were never on your PC than plug your iPod in, hit sync, and it should ask if you would like to transfer the items on you iPod to your computer so hit transfer
open itunes and sync
Plug your ipod touch into itunes and click sync.
Depending on what format your songs are in, it should most likely be able to transfer onto your iPod.
Forever, until you get rid of them that is. You can do this on itunes on your PC or, if you've got an iPod touch, you can delete them on there.
Firstly, in iTunes, select "manually manage songs and videos" beforehand so that when you connect your iPod to another PC it wont erase everything. Second, download iTunes on your new PC. Third, save all of your songs from your old PC to a CD or something so you can rip it to your new PC. Once you have done that you can use your iPod on a new PC.
The only way I believe I believe that you can do this is too plug the other persons iPod into your PC / Mac and place the songs onto it from there.
Convert them first. if the songs format is not right, you have to convert first.
