you have to hack into your ipod/computer, by allowng hidden files to be shown. i had to do this a few times and it works great :)
open up terminal using the spotlight search
type in: defaults write com.apple.Finder AppleShowAllFiles TRUE
then type in: killall Finder
you will see a bunch of folders with a number sequence click on each folder individually, your songs will be in each folder labeled with a four letter code (ie: GDAI) with no relation to the track title. Select all files in the folder and drag to itunes library, where most files will automatically recover their name and info. Some files do not convert and so you have to go through and rename them. Also, take your time doing this, wait for each folder to load completely, when you rush copying you will forget a folder and lose songs..I've done that a lot.
After you are done re-enter the same terminal code as above but change the TRUE to FALSE and your hidden files will disappear.
