We have rules around here regarding radio control, and it's because my brother and I have had passengers that dink around with our radio while we're driving. So now the driver controls what everyone listens to in the car. If the driver feels like listening only to the intros of songs, then that's what everyone has to put up with.
As for music that's good for driving, usually up-tempo (as in faster paced and not melancholy) stuff is great for that, as it helps keep me focused and alert, but aside from those criteria, just about anything I feel like listening to at any given moment works.
