private function loadmp3():void{
aRequest = new URLRequest("Wake.mp3");
mp3s = new Sound();
mp3s.load(aRequest);
trace("try load");
mp3s.addEventListener(Event.ID3,getID3);
private function getID3(event:Event):void{
trace(event.target.id3.artist);

I've had the same problem, and I solved it by by asking my ListSelectionEvent's getValueIsAdjusting() method:
rowTypeSM.addListSelectionListener(new AbstractListSelectionListener(){
public void doValueChanged(ListSelectionEvent e){
if(!e.getValueIsAdjusting()){
// Stick your code here
Hope this helps.
