Loading Multiple External Music Files

I am working on a photo gallery with music and everything works good except I can not seem to load multiple music files one right after another. This is the code I have that works with one music file. If someone can please help me be able to load another after the first song ends that would be great?

Oops! I forgot to add the actionscript code. Here is what I got right now:


var music:Sound = new Sound(new URLRequest("WeddingPage.mp3"));
var sc:SoundChannel = music.play(0,int.MAX_VALUE);
var isPlaying:Boolean = true;
var pos:Number = 0

//---Music Off Button---//

musicOff_btn.addEventListener(MouseEvent.CLICK, stopMusic);

function stopMusic(e:Event):void
{
if (sc != null)
{
sc.stop();
pos = 0;
isPlaying = false;
}
}

//---Music On Button---//

musicOn_btn.addEventListener(MouseEvent.CLICK, playMusic);

function playMusic(e:Event):void
{
if(!isPlaying)
{
sc = music.play(pos);
isPlaying = true;
}
}

//---Music Pause Button---//

pause_btn.addEventListener(MouseEvent.CLICK, pauseMusic);

function pauseMusic(e:Event):void
{
if(isPlaying)
{
pos = sc.position;
sc.stop();
isPlaying = false;
}
}

//---Volume Slider---//

var dragging:Boolean = false;
var rectangle:Rectangle = new Rectangle(0,0,100,0);
volume_mc.slider_mc.addEventListener(MouseEvent.MO USE_DOWN, dragIt);
stage.addEventListener(MouseEvent.MOUSE_UP, dropIt);

function dragIt(e:Event):void
{
volume_mc.slider_mc.startDrag(false,rectangle);
dragging = true;
volume_mc.slider_mc.addEventListener(Event.ENTER_F RAME, adjustVolume);
}

function dropIt(e:Event):void
{
if (dragging)
{
volume_mc.slider_mc.stopDrag();
dragging = false;
}
}

function adjustVolume(e:Event):void
{
var vol:Number = volume_mc.slider_mc.x / 100
var st:SoundTransform = new SoundTransform(vol);
if (sc != null)
{
sc.soundTransform = st;
}
}
