import processing.sound.*;

SoundFile sound;

void setup(){

  size(800,600);

  sound=new SoundFile(this,"hello.mp3");

  sound.play();

  sound.loop();

}

(2)

import ddf.minim.*;

Minim minim;
AudioPlayer player;

void setup(){
  size(800,600);
  minim=new Minim(this);
  player= minim.loadFile("hello.mp3",2048);
  player.play();
}
void draw(){

}
