I never saw this thread before. Thanks for reviving it.
Oddly enough, I never would've driven a car without listening to music before...but now that I have the hybrid, I often drive while listening only to its uniquely hybrid sound effects. How dorky is that?
Music-wise I listen to a mix of classic/hard/punk/alternative and Celtic rock. When I'm not listening to that "whirring" and such.

If you're not part of the solution, you're part of the precipitate.
