if you have a PC
plug the iPod into itunes and make sure it doesn't update anything
go to 'preferences' and the 'iPod' tab and hit 'enable disk use'
now go to 'my computer', you should see your iPod as an external hard drive,
hit the 'tools' marker on the top left, and 'folder options'
go to the 'view' tab and select "Show hidden files and folders"
now go into your iPod folder on 'My Computer' and the 'iPod Control' folder
then 'Music'
and you should see folders that read "F00" through "F49". That is the music on your iPod
now copy and paste all of the contents in that area to where you want it.
Hopefully, you've now copied all of the songs off of your iPod to your computer
