Good music. I don't know if it's same with everyone one, but for me listening to some hardcore rap/pop especially with the speakers blaring and glad rolled up.

I tend to hit the gas hard at certain stage in the music. Usually the highpoints of the music. It creates a sort of sensation for me. Singing aloud with the song being played and hitting the gas to correspond with the song melody.

I know I am not the only one with this. I know many people will also do that
