Whether you can drive or not, what kind of music do you like to listen to when you're in the car? Any specific style or artist you think is more interesting to listen to while you're driving opposed to just being around at home, or is it always the same kind of style or band no matter where you go? Or maybe you don't like listening to music while you drive (if you don't like listening to music at all, you might be in the wrong section), whatever works.
I listen to alot more Classic Rock/Blues while I'm driving (I listen to it quite a bit when I'm at home too, but it just seems to sound better in the car). Whether or not I've got a CD in or am listening to the radio, that's usually the kind of stuff I've got on while I drive.
