Sound Issus

Hi there, I'm currently facing a problem with my background sound file. I coded it like that. 
Greenfoot.playSound("track.mp3");
and it works fine for the moment, but after like 1 min in the game, the game becomes very laggy. I once had the same issue with my pictures, I solved it with setting it final in the field like that. 
public static final GreenfootImage picture1 = new GreenfootImage("picture.png");
and I've heard that there is a similar way to do this with sound files, but couldn't find a proper solution so far. The sound file I'm using is .mp3 (3.5Mb) and I've removed all the tags. I also tried it with a .wav file, but it doesn't work either.

When you comment out the 'playSound' line, does the lag in the game disappear?

Yes, but in this case I have no more sound

Then it is not a sound issue. It is either excessive image creating/manipulating or excessive actor creating. Stop the scenario after lag shows up and right click the world and select the inherited World method 'numberOfObjects' and see what is returned.

It says 40, is that too much?

Only if most of them are updating their images constantly. May have to go through each of your act methods to see what is going on. If you want to go through each one, start with your world class code.

There is only one actor that is animated, everything else is at a fixed location with default image settings. Well I'm using your "srcolling Superworld", is there something I need to add for sound?

Why exactly isn't it a sound problem if the problem stops when the sound is commented out?

Actually I just figured out "why" it's lagging ... my 8*4.6GHz Prozessor is running at a 100% when I play the game..^^ something is wrong :( When I comment out the "playsound", it is at 8%..

Do you start the music only once?

No indeed I start it every act cycle. How do I create the sound in the World class? Storing it like 
GreenfootSound track1 = new GreenfootSound("background.mp3");
but how would I create it?

Sorry, when I was answering that, I was thinking the opposite case (the problem remaining instead of disappearing).
