Use the following ( I named first world MyWorld and sound file intro.mp3 ):
?
1
public static GreenfootSound bgSound;
and in constructor ( public MyWorld() ):
?
1
2
bgSound = new GreenfootSound("intro.mp3");
bgSound.play();
In any class in your project, you can then use:
?
1
MyWorld.bgSound.stop();
To change it, replace what the field references::
?
1
2
MyWorld.bgSound = new GreenfootSound("replacement.mp3");
MyWorld.bgSound.play();

You could go as far as putting the following the the MyWorld class:
?
1
2
3
4
5
6
7
public static void setBackgroundSound(String name) {
    if (bgSound != null) bgSound.stop();
    bgSound = null;
    if (name == null) return;
    bgSound = new GreenfootSound(name);
    bgSound.play();
}
In the constructor, you could then just have:
?
1
setBackgroundSound("intro.mp3");
Then, to change it from anywhere:
?
1
MyWorld.setBackgroundSound("replacement.mp3);
You can also stop and discard the background sound altogether with:
?
1
myWorld.setBackgroundSound(null);
