If all your audiobooks are scratched and NPR is taken over by terrorist monkeys, what would be your driving-in-the-car music?
Damn, dirty monkeys.
Actually, sometimes I *do* listen to music in the car. Often after any kind of social event, I'm too stressed to concentrate on audiobooks or podcasts, so it's music instead. Generally, though, I like driving to the same innocuous & sadly-outdated pop music I always listen to; often I just put the iPod on shuffle and let it go.
