ActionScript 3.0 :: Audio Toggle - Mute / Play Music Again In SWF?

I call it a hiccup because the code works; but it's backwards. When I hit the audio button it plays the music and when I hit it again it stops the music. I wish for the music to play automatically when you enter the SWF and then you hit the button to mute the music if you wish; and then hit the button again to play the music again.

Here is the code I have:
toggleButton.addEventListener(MouseEvent.MOUSE_OVER, rolloverToggle);
toggleButton.addEventListener(MouseEvent.MOUSE_OUT, rolloutToggle);
toggleButton.addEventListener(MouseEvent.CLICK, toggleClick);
toggleButton.buttonState = "On";
var song:Sound = new TitleMusic();
[Code] .....
