iPod Music Xfr from iPod to Mac-Mini?

This morning, I had some issues with Tiger on my Mac-Mini, and essentially had to do a full erase and revert back to Panther. I was able to backup most of my stuff, but my MP3 library bit the dust. Can anyone recommend a solid method of transferring the library on my iPod back to the Mini?

I know this appeared several times in the forums, but couldn't find anything. Thanks in advance.

I was able to copy everything over..except an audiobook I bought off iTunes...It seems to be in one of the "invisible" folders on the iPod...and idea how I might access it so I can copy it over?
