Why doesn't this stop?

It should stop the song, but it doesn't?

local sound = game.Workspace.Part
local enable = true
local sound2 = game.Workspace.Part.Sound

function Clicked()
    if not enable then return end
    enable = false
    sound.Sound:Play()
    wait(sound.Sound.TimeLength)
    sound.Sound:Stop()
    enable = true


if sound.Sound2.IsPlaying == true then
        sound.Sound:Pause()
        end

end
