How can I restore the music that was on my iPod to my computer or another iPod?

My iPod classic has failed with an HDD error. I've tried recover mode and everything, it's goosed. Half my music was only on the iPod, a collection over the years from my various computers, it was backed up using itunes however. How can i restore the music that was on my iPod to my computer or another iPod? (dont have another classic, only shuffle and iphone) I'm guessing itunes holds some kind of virtual image of the ipod classic somewhere. THanks in advance for any info, google didn't produce anything I could use.
