No, I would not agree that music defines Driving Style.
I can drive whatever style I like without music, which is most of the time the case.
However, I like rock-pop, sometime dance, R&B. Also, I fall into classical. And I must admit, many times classical can trigger more sport-ish driving emotions on the road than "normal music".
So it is not so straight that one music will create one style.
All in all. The most I enjoy is listening to my car.
