Play new sound in every frame

I have the following code that plays an mp3 on the first frame. When complete, it goes to the second frame.

Is it valid to put similar code in my the second frame of the my actions layer? (just adjust var names and such).

It works, I just want to know if its in best practice.

var soundReq:URLRequest = new URLRequest("path1_a.mp3");
var sound:Sound = new Sound();
sound.load(soundReq);
 
sound.addEventListener(Event.COMPLETE, onComplete);
sound.addEventListener(Event.SOUND_COMPLETE, soundFinished);
 
function onComplete (event:Event):void {
        sound.play();
}
 
function soundFinished (event:Event):void {
        gotoAndStop(2);
}
