NetConnection/NetStream Mp3's?

Hey,

Im having problems with playing a mp3 from a streaming url, this is my first time using the NetConnection class and my actionscript knowledge is pretty basic. I’ve found alot of online reference to using this for .flv but theres nothing out there really for mp3’s. So, my NetConnection.onStatus is returning “connected” but i can’t figure out how to actually access and be able to hear the mp3. Is there somthing blatantly obvious that im missing??? If anyone is able to help, that’d be great!


stop();

nc = new NetConnection();
nc.connect("RTMP://*****.fcod.llnwd.net/a2934/");
nc.onStatus = function(info){
    if (info.code == "NetConnection.Connect.Success") {
        trace("connected");
        playIt();
    }    
    else {
        if (! nc.isConnected){
            trace("not connected");
        }
    }
};
function playIt(){
var ns:NetStream = new NetStream(nc);
ns.setBufferTime(0);
ns.play("o28/Tracks/7780/******440240c179b847c18d33cb57e717ded9.mp3"); 
test_mc.attachAudio(ns);
testSound = new Sound(test_mc); 
testSound.setVolume(100);

}

getTotalTime = function () {
    ns.onMetaData = function(obj) {
        _global.videoDuration = obj.duration;
        trace(obj.duration);
    };
}
onEnterFrame = function () {
    getTotalTime();
    totalPlayingTime = Math.round(_global.videoDuration);
    currentPlayingTime = Math.round(ns.time);
    if (currentPlayingTime>.01) {
        test_mc._x = 0;
        test_mc._y = 0;
    }
    if (totalPlayingTime == currentPlayingTime) {
        ns.seek(0);
        ns.pause();
        //ns.close();
        trace("song end");
    }
};
