I like to listen to short books (45-60 minutes) while I'm falling asleep. Some of my books stop after they have completed. I thought they all did, but I have discovered that some of them just continue on to the next (sometimes really lengthy!) book. Just couldn't figure out why the battery on the iPod would be dead after just a couple of night's use, until I accidentally discovered what was happening.

How can I get all audiobooks to stop at the end? Until I get this figured out, I've been using the "sleep" function, but it would be more convenient to skip this step.

PS. If it matters -- all of my audiobooks are from Audible.
