Ive had a very similar experience. My laptop died on me and then while shifting some heavy boxes I crunched in the screen of my old iPod classic. It was a 60gig model and while I was prepared to lose out on the 5/6gigs that didnt make the cut adn was on the harddrive I wasnt prepared to lose out on the 60gigs and go through another ripping of the library.
I cant remember the name of the software (sorry) but it is very easy to download and it basically decodes Apples filing system and keeps all track details and sound quality. Basically turns it temporarilly into a portable hard drive.
So, dont worry too much you'll be able to get your tunes back nae bother with a quick google search.
