Is it possible to have a button for music on and off and it will actually turn music on and off just by a click of the button

It is is very easy to make. first you need to have a Boolean to control the music and keep track of the clicks. for example I did something like 
boolean playMusic = true;
then you will need to import the sound 
 GreenfootSound sound = new GreenfootSound("Name.FileFormat");
then you will need to get the sound icon and make an image. 
GreenfootImage music= new GreenfootImage("images/speaker.png");
on act method you can write something like 
 if (Greenfoot.mouseClicked(this) && !playMusic) {
           playMusic = true;
        } else if(Greenfoot.mouseClicked(this) && playMusic){
           playMusic = false; 
        }
        

    if(playMusic){
        sound.playLoop();
    } else{
        sound.stop();
    }
setImage(img);
You can change the image when the playMusic is true or false as well

# 
boolean playMusic = true;
GreenfootSound sound = new GreenfootSound("Name.FileFormat");
// write the location, name and file format of your music file
GreenfootImage music= new GreenfootImage("images/speaker.png");
// write the location, name and file format of your image file

public void act(){
if (Greenfoot.mouseClicked(this) && !playMusic) {
           playMusic = true;
        } else if(Greenfoot.mouseClicked(this) && playMusic){
           playMusic = false; 
        }
         
 
    if(playMusic){
        sound.playLoop();
    } else{
        sound.stop();
    }
setImage(img);
}

Maybe you can take example from my BgMusic Actor Class Demo scenario, which you can run to view the code. It is also down-loadable.
