What is wrong with my code? It doesn't work. Cdfdfsdfdfsdfdf

Here is my localscript code; inside the startergui:

local RemoteEvent = game.Workspace:WaitForChild("Music"):WaitForChild("RemoteEvent")
local player = game.Players.LocalPlayer
canplay = true

RemoteEvent.OnClientEvent:Connect(function()
	if canplay then
    local sound = player.PlayerGui:WaitForChild("sound")
    sound:Play()
    sound.Looped = true
    print(otherpart)
canplay = false
end 
end)

Here is my script code inside the workspace:

local part = game.Workspace.Music
local RemoteEvent = Instance.new("RemoteEvent", part)
local sound = game.Workspace["Final Boss"]
canplay = true 

local function muziekspelen(otherpart)
    print(otherpart)
    local humanoid = otherpart.Parent:FindFirstChild("Humanoid")

    if humanoid and canplay then
        local player = game.Players:GetPlayerFromCharacter(otherpart.Parent)
        canplay = false
        RemoteEvent:FireClient(player)
sound.Parent = player.PlayerGui
sound:Play()
sound.Looped = true

    end
    canplay = true
end

part.Touched:connect(muziekspelen)

I don't want to repeat the sound everytime it's being touched by the localplayer. Does anyone know how to do this?
