Making a music script use a table???

local Sound = script.Sound
local ContendProvider = game:GetService("ContentProvider")

local MaxSound = 2

local CurrSound = 0

local Music = {
	551334045,
	1524396093,
	627848963,
	
}




while true do
	if CurrSound <= MaxSound then
		Sound.SoundId = "rbxassetid://"..Music[CurrSound]
		CurrSound = CurrSound + 1
		Sound:Play()
		Sound.Ended:Wait()
	else
		CurrSound = 0
	end
