(AS3) Sort and Sound.play() issues

Question

There are over 2000 songs in the remote directory.In this case, might "sound.play()" be executed first before "sort()" completes?So is there a way to prevent this?I would greatly appreciate it if you could let me know the sample code. var channel: SoundChannel;
var sound: Sound;
var n:uint;
var dm: String = "http://.../Music/";

var sm: Array = [ Music list of over 2000 songs ];
sm.sort(1);

n = Math.floor(Math.random() * (sm.length-1));
musicPlay(sm[n]);

function musicPlay(url: String): void {
	if (channel) channel.stop();
	n = sm.indexOf(url);

url = dm + url + ".mp3";
	sound = new Sound(new URLRequest(url));
	channel = new SoundChannel();
	sound.addEventListener(ProgressEvent.PROGRESS, progressHandler);
	channel = sound.play(0);
}

code after the sort() won't execute until sort completes. it's easy to confirm:

var a:Array = [];

var n:int = 100000;

var alphaS:String = "abcdefghijklmnopqrstuvwxyz"

var alphaA:Array = alphaS.split("");

for(var i:int=0;i<n;i++){

a.push(alphaA[Math.floor(Math.random()*alphaA.length)]+alphaA[Math.floor(Math.random()*alphaA.length)]+alphaA[Math.floor(Math.random()*alphaA.length)]+alphaA[Math.floor(Math.random()*alphaA.length)]+alphaA[Math.floor(Math.random()*alphaA.length)]);

}

trace(a);

trace("\n\n\n");

a.sort();

trace(a);

");a.sort();trace(a);
