I hear mostly Rock music in the car. I prefer bands like Disturbed, Metallica, and Linkin Park for the more recent bands. The older stuff I like is Rush, Bon Jovi, Def Leppard, Black Sabbath, Pink Floyd, Aerosmith, stuff like that.
I rarely hear rap for 2 reasons: 1.) I hate rap 2.) so do most of my friends and family.
