Flash XML AS3 MP3 Player

programming flash

I have built an MP3 player using XML and this works fine. But I want this MP3 player to load a random song from the XML list everytime it runs. I have this code

var my_songs:XMLList;
var my_total:Number;
var my_sound:Sound;
var my_channel:SoundChannel;
var current_song:Number = 0;
var song_position:Number;
var song_paused:Boolean;

var myXMLLoader:URLLoader = new URLLoader();
myXMLLoader.load(new URLRequest("playlist.xml"));
myXMLLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(evt:Event):void
{
    var myXML:XML = new XML(evt.target.data);
    my_songs = myXML.SONG;
       
        for(var i=0;i<my_songs.length;i++) {
            var randomSong = Math.floor(Math.random()*my_songs.length);
            var t = my_songs*;
            my_songs* = my_songs[randomSong];
            my_songs[randomSong] = t;
            }
    playSong(randomSong);
}
 
function playSong(mySong:Number):void
{
    var myTitle = my_songs[mySong].@TITLE;
    var myArtist = my_songs[mySong].@ARTIST;
    var myURL = my_songs[mySong].@URL;
    trace(my_songs[mySong].@URL)
    title_txt.text = myTitle;
    artist_txt.text = myArtist;
    if(my_channel)
    {
        my_channel.stop();
    }
    my_sound = new Sound();
    my_sound.load(new URLRequest(myURL));
    my_channel = my_sound.play();
    my_channel.addEventListener(Event.SOUND_COMPLETE, nextSong); 
}

next_btn.addEventListener(MouseEvent.CLICK, nextSong);
function nextSong(evt:Event):void
{
    current_song++;
    if(current_song >= my_total)
    {
        current_song = 0;
    }
    playSong(current_song);
}

prev_btn.addEventListener(MouseEvent.CLICK, prevSong);
function prevSong(evt:MouseEvent):void
{
    current_song--;
    if(current_song <= 0)
    {
        current_song = 9;
    }
    playSong(current_song);
}

pause_btn.addEventListener(MouseEvent.CLICK, pauseSong);
function pauseSong(evt:MouseEvent):void
{
    song_position = my_channel.position;
    my_channel.stop();
    song_paused=true;
}

play_btn.addEventListener(MouseEvent.CLICK, play_Song);
function play_Song(evt:MouseEvent):void
{
    if (song_paused)
    {
        my_channel = my_sound.play(song_position);
        song_paused = false;
    }
    else if (!my_channel)
    {
        playSong(current_song);
    }
}

but it produces the error -

Error #2044: Unhandled IOErrorEvent:. text=Error #2032: Stream Error.

I have also tried to trace the problem by putting trace(my_songs[mySong].@URL) in the playSong() function but this doesn’t do anything. Can anyone help?
