2 ipods with one problem

I just got the new ipod nano video but still have the 80GB ipod video also. I was wondering how can I place music that I want on the new nano with out downloading unwanted music and also keeping my music on the computer?

 

OK on your itunes all your music have a little check mark next to them, you have to manually ckeck off the ones you dont want, and then on itumes click only sync song that have check mark on them.

 

or you could just make so that they dont sync and put the songs on that you want instead of unchecking each song
to make it so they dont sync, when you plug in the ipod go to the device and then to the music tab then uncheck the aotunaticly sync box

 

Yea, that works too, ither way will give you the same result.
