music while driving

I am mostly listening to FM or CD while driving. And strangely the volume and type of music controls the speed at which I am driving. Generally if there is some party song, I will play at high volume and tendency will be to drive faster also :-). But dont worry, I am a very safe driver. And then driving at full volume with windows closed has one advantage, I dont have to bother about the fellas who unnecessarily honk.
