Any help on what to put into this script?

Try this:

local Clicked = false

function onClick()
	Clicked = not Clicked
    while Clicked do
        script.Parent.Parent.Sound1:Play()
        wait(120)
        script.Parent.Parent.Sound1:Stop()
        wait(.1)
        script.Parent.Parent.Sound2:Play()
        wait(120)
        script.Parent.Parent.Sound2:Stop()
        wait(.1)
        script.Parent.Parent.Sound3:Play()
        wait(120)
        script.Parent.Parent.Sound3:Stop()
        wait(.1)
        script.Parent.Parent.Sound4:Play()
        wait(120)
        script.Parent.Parent.Sound4:Stop()
        wait(.1)
        script.Parent.Parent.Sound5:Play()
        wait(120)
        script.Parent.Parent.Sound5:Stop()
        wait(.1)
        script.Parent.Parent.Sound6:Play()
        wait(120)
        script.Parent.Parent.Sound6:Stop()
        wait(.1)
    end

	if not Clicked then
		script.Parent.Parent.Sound1:Stop()
		script.Parent.Parent.Sound2:Stop()
		script.Parent.Parent.Sound3:Stop()
		script.Parent.Parent.Sound4:Stop()
		script.Parent.Parent.Sound5:Stop()
		script.Parent.Parent.Sound6:Stop()
	end
end


script.Parent.ClickDetector.MouseClick:connect(onClick)

In theory it should work.

What it does is that when the player click the ClickDetector, the "Clicked" becomes either true or false based on its pervious value. If "Clicked" becomes true, it plays the while loop until it becomes false, and when it becomes false it stops all the music.
