YOU DONT NEED A PROGRAM:
it is hard to do though kinda....
plug in your ipod, go to my computer, click on removable disk should say your ipod name.
tools;folder options;view;show hidden files and folders
now hit x and go back to it there should be a folder that is like opaque, i think it says music or something i dunno but click it there are like 5 diff. folders drag the music one to your desktop and theyll go to your itunes.
if you cant drag it to your desktop:
open itunes;file;add file to library
find that file i mentioned above click it till all these subfolders come up that are like F00 F01 etc.
shift down till that list is done, you have to do it like a bunch of times so yeah this way sucks more.
i havent done this in forever so lemme know if it works if you use it....
