I have a 120GB Ipod classic and I would like to sync my Ipod with the Itunes on my computer. The Ipod was last synced on another computer and has roughly 5200 songs. What would happen if I just plug the Ipod into my computer will the music on that computer be replaced? Or will the music on the Ipod be replaced? Or another scenario I have no idea, and if one of these does happen is there a way to make my Ipod add it's current music to my itunes and combine the two??
