How Do I Put Music From One Ipod To Another?

I came across the same problem when my sister the same iPod as mine.
Not long ago, I found this iPod to iPod transfer program. It solved my problem.
It enables us to copy files among multiple iPods at one time. Simply connect two iPods to pc and then you can draw and drop files between them.
Besides, it can help us transfer all files from iPod to iTunes, iPod to computer as well as from computer to iPod.
It works like a charm. You may give it a try.
