How can I change my background music when I change from world to another? What would the code be?

Well, if this is following through on your teleporting question I answered, change the teleport method I made to something like this (note, i haven't used sounds yet, but I got my information from the greenfoot api: http://www.greenfoot.org/files/javadoc/):
private GreenfootSound song;
...
public /*World name*/(GreenfootSound s //...)
{
...
song = s;
song.play(); //or song.playLoop() if you want to go on continously
}
public void teleport()
{
song.stop();
//everything from your last question
}I change worlds in my actor class and my music is playing in the first world. I want the music to change in the second world.
did you make sure to stop the song before switching worlds?

I don't have any code for it, my music in my world it set to stop when game stops and my game stops when character dies.
alright. That's what I thought. Well, I haven't personally used GreenfootSound, but it should stop when you tell it to stop... Here's another question: Is your GreenfootSound object an instance variable (one of the private variables at the top of the class) in your world class?
alright, so before you switch, you need to call the method stop somewhere. I'm guessing if you're using your teleport method as well, you should add this to your world:
Then in your teleport code in the player:
public GreenfootSound getSound()
{
return mySound; //Or whatever you called it
}public void teleport()
{
getWorld().getSound().stop();
...

}oops, gotta cast your world.
Pretend your world is named: "GreenfootWorld"
The reason you get an error is because the normal World does not have a method called getSound(). You created it in GreenfootWorld. Therefore, you must cast getWorld() (which is of World) to GreenfootWorld with the code above
//Change getWorld().getSound().stop(); //to ((GreenfootWorld)getWorld()).getSound().stop();
Now the sound stops but the second level sound doesn't start unless I pause the game and run it again
put an act() method in your world, and do this:
and then take out the line in the constructor that says play.
public void act()
{
if (!songName.isPlaying())
songName.play();
