Play button stops the current sound but doesn't play another as intended. What should I do?

I am trying to make it so when a Play button is pressed, it stops the current sound and plays another sound. With this script it stops the current sound but it doesn't play the other sound. What's wrong with it?

FULL SCRIPT:

wait (0)
script.Sound:Play()

local PlayButton = script.Parent.PLAY

repeat wait()
    Camera.CameraType = Enum.CameraType.Scriptable
until Camera.CameraType == Enum.CameraType.Scriptable
Camera.CFrame = workspace.CameraPart.CFrame

PlayButton.MouseButton1Click:Connect(function()
    Camera.CameraType = Enum.CameraType.Custom
    PlayButton:Destroy()

wait (0)
    script.Sound:Stop()

wait (0)
    script.Sound2:Play()

end)
