How to give a button multiple functions

Question

So I have a button for audio which plays it and a button that stops the audio. What would I need to do with the actionscripting to hide the play audio button when the music is playing and just show the audio off button, and then hide the off button when it's clicked and show the play button in its place?

import flash.events.MouseEvent;
play_btn.addEventListener(MouseEvent.CLICK, playFunc);
stop_btn.addEventListener(MouseEvent.CLICK, stopFunc);
play_btn.x=stop_btn.x;
play_btn.y=stop_btn.y;
stop_btn.visible=false;
function playFunc (e:MouseEvent):void {
    play_btn.visible=false;
    stop_btn.visible=true;
    //the code to play
function stopFunc (e:MouseEvent):void {
    stop_btn.visible=false;
    play_btn.visible=true;
    //the code to stop
