Music is the most powerful sound there is, often inappropriately deployed. It's powerful for two reasons: you recognize it fast, and you associate it very powerfully.

The human voice: It's the instrument we all play. It's the most powerful sound in the world, probably. It's the only one that can start a war or say 'I love you.' And yet many people have the experience that when they speak, people don't listen to them.

Sound is complex; there are many countervailing influences. It can be a bit like a bowl of spaghetti: sometimes you just have to eat it and see what happens.
