title: How can I stop music from playing multiple times when going back to the frame it starts from in as3?
body: <p>I have a music track that starts on the first frame and plays throughout the entire application. When I go back to the first frame, the current music is still playing but the song starts again over the top of it. How can I make it so it only plays through once even after going back to that frame?</p>
  
  <p>My code:</p>
  
  <pre><code>var mySound:Sound = new Sound();
  var myChannel:SoundChannel = new SoundChannel();
  
  mySound.load(new URLRequest("Stellardrone - Billions And Billions.mp3")); 
  myChannel = mySound.play(); 
  SoundMixer.soundTransform = new SoundTransform(0.4); 
  </code></pre>
