If all you want to do is recover your music library from your iPod back to your computer, iPod -> Folder is probably the simplest way to do it. Just fire it up, point it to your iPod, point it to a folder on your computer, and let it rip. It even has a "Include MP3 files only" option in case you're borrowing tunes from a friend's iPod and you don't want their DRM-infected files.
