1. you have to have your computer authorized. to do that, open itunes , at the top of the screen right where it says itunes, click store, and a drop-menu appears. click authorize computer. 2. you also have to have your ipod on manually manage music. to do that, plug your ipod in on the first computer you plugged it in to sync it, and open itunes, click the ipod icon that says "your names ipod" on the pane on the left of the screen and then click manually manage music, and then click apply.

what i did w/ my 3 computers.

p.s. on the new computer, i think it will automatically put the songs from your ipod on the new computer. if not, click file, and then transfer purchases from ipod.
