I would like to stop the sound from playing when it gets to Gamover(game over), but it wont stop. Here's the code for Level1 (World) and Gamover(game over)
  import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
 * Write a description of class Level1 here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class Level1 extends World
{
     GreenfootSound myMusic = new GreenfootSound("Dragon Ball Z Budokai 3 Opening Theme _Full Version_ _HQ_ U.S Version.mp3");
    Scoreboard counter = new Scoreboard();
    
    /**
     * Constructor for objects of class Level1.
     * 
     */
public Level1()
    {   
    
        super(600, 400, 1); 
         Beginning aworld = new Beginning();
            Greenfoot.setWorld(aworld);
    }
public Level1(boolean second)
    {   
    
        super(600, 400, 1); 
        
        addObject(new Player(), 200,200);
        addObject(counter, 100, 40);
    }
    public Scoreboard getScoreboard()
    {
        return counter;
    }
public void act()
{
    if(Greenfoot.getRandomNumber(1000) <20)
        {
            Enemy e = new Enemy();
            addObject (e,
    Greenfoot.getRandomNumber(getWidth()-20)+10, -30);
        }
    
     myMusic.playLoop();
            
    
    }
   
}
import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

public class Gamover extends World

        super(600, 400, 1); 
        if(myMusic.isPlaying())
        {
            myMusic.stop();
        }
    }
        
    public void act()
    {
       myMusic.stop();
        if (Greenfoot.mouseClicked(this))
        {
            
            Beginning aworld = new Beginning();
            Greenfoot.setWorld(aworld);
        }
