I'm with you Coelho, I get pacified by tranquil silence when others would be pacified by filling the audio space with music or other noise. Music has specific effects on brain activity, such as a certain song was played more than once when a certain person was near, and hearing it again provokes a strong nostalgic feeling for that person or people, etc. I've noticed that most genres of music elicit their own unique neurological response, independent of personal attachments. One notable exception would be classical. I tend not to feel emotion with classical, but strokes of intellectual and creative activity in other areas of my brain.

When it's silent the roles are reversed and I am vulnerable to my brain's whimsy. If it starts going in the direction of trivial, immediate personal concerns I can shift it toward the ethereal, philosophical, political, scientific, etc. I don't claim to be any influential pundit in those areas, but I enjoy the science of thought.
