Can you download from your iPod to your computer and then to another iPod?
There are many ways to download between iPod-Computer and Vice
Versa. If you want to put something from your iPod to your
computer, you can connect it to your computer, and in iTunes,
right-click on your iPod, and click "Transfer Purchases". Once
those are all downloaded to the computer, you can drag them to a
new iPod!
