Humanoid Death Sound Playing only on Spawn?

So I have a sound in a Monster's head in workspace. When the humanoid of that monster dies, the sound plays.

The problem is that it only plays when the Monster spawns, and not when it dies.

Here's the script

if script.Parent.Parent.Humanoid.Died then
	


	script.Parent.Roar:Play()
	
end

I ALSO have A script that preloads the sound, which is

Assets = {131172401}
 
for _, asset in ipairs(Assets) do
     Game:GetService("ContentProvider"):Preload("http://www.roblox.com/asset/?id=" .. asset)
end

(I know that you already solved your problem, but I want to explicitly answer it for the sake of curious readers.)

Use the died event to fire the function specifically for playing the sound. You can do this with a separate connection line, or anonymously (meaning no name).

Separate Connection Line:

function MonsterDead()			-- function 'MonsterDead' with no arguments
	script.Parent.Roar:Play()		-- Plays the sound
end

script.Parent.Parent.Humanoid.Died:connect(MonsterDead)	-- When the humanoid dies, MonsterDead is triggered

Anonymously:

script.Parent.Parent.Humanoid.Died:connect(function ()		-- There's no name on this function; basically a function in the connect method (making the function the argument of the connect method)
	script.Parent.Roar:Play()		-- Plays the sound
end)
