To keep people from easily tranfering songs from person to person (copywright stuff) the Ipod and your new computer will not get along unless you let it configure your ipod thus erasing all the lovely songs and playlists you currently have. I got the jones deal when my older ipod crashed and I had to get a new one. In your old computer lies the actual mp3 or wave files you need to locate them and either transfer them to an external hard drive or burn them to cd and import each one of them over to your new emac's itunes, they will get stored in your itunes library then you can add them to your recently erased and properly addressed ipod. Hope this helps Mp2
