Background music has to loop

[freddieclub]

Hello all people!

I made a MP3 player that plays an XML playlist (spoken text) mixed with background music. So essentially both play at the same time. The mp3 player is a custom version of John Bezanis mp3 player (recommended!), available at http://www.swfspot.com
I want to loop the background music. Here's were i'm stuck: it doesn't!

there's alot of code, but here's the background music part:
var mySound:Sound = new Sound();
mySound.loadSound(_root.backgndMusic,true);
mySound.start(0,100); // start background music in loop

The code is in Frame3.

Any help greatly appreciated!
