I have looked around but cannot find much about this. my game ha 3 levels and I want it to play different bg music for each level. so far I have the level1 code but for some reason when I go to level 2 it continues to play the music from level 1 at the same time as the music from level 2. level 1 music will pause when I pause the game but only on level 1. level 1 code 
import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

public class Level1 extends World
{
    GreenfootSound backgroundMusic = new GreenfootSound("level1 theme.mp3");

    private int [] [] mazeMap = {

I also have a problem where each time I die the music keeps going but ads more music from the beginning. (when I die it sets the world to whatever level I am on).

The 'stopped' method is called in the active world when the scenario was paused, not when the world changes. You have to stop the music before setting the new world.

As an alternative, you can utilize by BGMusic class to control the background music of your scenario. You can find it in my BGMusic Actor Class Demo scenario.
