It's not the library that shipped with Processing. I looked it up and it said you had to use this program to play sound, so that's what I did.
[snip java]
import ddf.minim.*;
Minim minim;
AudioPlayer song;
void setup()
{
size(100, 100);
minim = new Minim(this);
// this loads mysong.wav from the data folder
song = minim.loadFile(“music.mp3”);
song.play();
}
void draw()
{
background(0);
}
void stop()
{
song.close();
minim.stop();
super.stop();
}

This is just the basic one I used to see what the heck was going on.
