How do i make a music changer part the doesnt restart the music after dying?

It is a part that when stepped on, will change the music to that sound id, it is not a gui.

local loop = true
local sound = "rbxassetid://622820644"

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local player = game.Players:GetPlayerFromCharacter(hit.parent) 
	game.ReplicatedStorage.Song:FireClient(player,sound)

	end
end)
