How can I make lights move to music, basically exactly like in Pulse Nightclub?

I'd like to make the lights in my game move up in down like they do in Pulse Nightclub. Can anyone tell me how, if you have seen it in game? ~iZacharias

Here's the script EDIT #3 Added the light

part = script.Parent
up = Instance.new("BodyVelocity")
up.Parent = part
light = Instance.new("PointLight")
light.Parent = part
light.Color = Vector3.new(85, 0, 255) --Blue
light.Range = 60
while true do
up.velocity = Vector3.new(0,2,0)
wait(5)
up.velocity = Vector3.new(0,-2,0)
wait(5)
end
