Ah I see. You're that guy in the movies who doesn't believe in zombies and walks right up to one while their friends are shouting 'No, Don't!' and 'Billy, come back!'... And later on they show up as a zombie.
I never saw music tried... I mean with Zombies. Like blare out music on loudspeakers and they all kind of freeze and listen enraptured, or grab their ears and fall on the ground writhing in pain. What music would work best?
