Hi!  
I am trying to play some songs that have been loaded from a XML file.  
The XML file is loading everything write.The problem is that when I first run my movie it plays the sound correctly but when I click a button to play another song it stops playing(because I asked to stop) and gives me an error without play another song.

```auto

var xmlLoader : URLLoader = new URLLoader();
var url : URLRequest = new URLRequest("songs.xml");
var Songs :Array = new Array();
var xSongs :XML;

var slc :SoundLoaderContext = new SoundLoaderContext(3000);
var S :Sound = new Sound();
var SC :SoundChannel;

xmlLoader.load(url);
xmlLoader.addEventListener(Event.COMPLETE,onLoaded);

music1.addEventListener(MouseEvent.CLICK,onMusic1CLICK);
music2.addEventListener(MouseEvent.CLICK,onMusic2CLICK);

function onMusic1CLICK(e:MouseEvent):void
{
   playSong(0);
}

function onMusic2CLICK(e:MouseEvent):void
{
   playSong(1);
}

function onLoaded(event:Event):void
{
   xSongs = new XML(event.target.data);
   var lSongs :XMLList = xSongs.song.attribute("url");
   
   for each(var Lista:XML in lSongs){
      Songs.push(Lista);
   }
   
   playSong(1);
   music2.visible = false;
}

function playSong(songID : Number):void{

   SoundMixer.stopAll();
   S.load(new URLRequest(Songs[songID]),slc);
    SC = S.play();      
   SC.soundTransform = new SoundTransform(0.7);
}

```

and the error message
