[F8] crazy music button

[belotte]

I have a MC "button" that loads an external mp3

the external mp3 is called "block_party.mp3"
the button instance is "song1".

can any one tell me why this doesn't work. My code is as follows:

__root.song1.onRelease = function() {
this.createEmptyMovieClip ("song1", this.getNextHighestDepth());
var song1:Sound = new Sound (mcSong1);
song1.loadSound("block_party.mp3", flase);
song1.onLoad = function (bSuccess:Boolean):Void {
if(bSuccess) {
this.start();
};
};
var nInterval:Number = setInterval (checkProgress, 500);
function checkProgress():void {
}
}

Thanks.
