Yesterday I tried iPod Util (download from
<http://www.versiontracker.com/dyn/moreinfo/macosx/14715>.

It gave me access to songs as well as voice memos.

I also tried iPod Viewer (download from
<http://www.versiontracker.com/dyn/moreinfo/macosx/15864>.

It gave me access to voice memos and items saved to my iPod as an external
hard-drive that I thought I had deleted, but not to songs.

They're both good, but iPod Util is a bit fiddly in that every track shows
up and you have to uncheck the tracks that you don't want to copy across.
