Stop music on level change?

Forgive my noob questions, but this is the situation:

I have my level set up with an object that starts the music when the level is started. So far so good. I'm doing this game through behaviors. Now all I need to know is where to put alxStop to stop the music before the new one is started. Scripting ain't really my thing, so forgive my unstructured script. :)

/* AUDIO PROFILE BEHAVIOR 
       by Joe Rossi
    
   This is my workaround to the TGB editor not having audio support in the editor.
  
   Add this behavior to an invisible staticSprite, or one off screen.  
   I personally use a sprite with a music note texture ;)
      
   When the level is loaded, it creates a new audioprofile.
   
   This will look in your game/data/audio folder for the sound
