HELP! How to play different audio files in one sketch?

Hey guys, On one hand, I'm trying to play 10 different audio files in one sketch with minim. On the other hand, I need the program to ignore every following mouse press if the player is playing until its done. However, I dont get how to set up the "false" command. I would be so happy if someone could take a look at my sketch and help me out! Thanks a lot.

import ddf.minim.*;

Minim minim;
AudioPlayer[] player;

String[] SONGS = {"Fact01.mp3", "Fact02.mp3", "Fact04.mp3", "Fact05.mp3", "Fact06.mp3", "Fact07.mp3", "Fact08.mp3", "Fact09.mp3", "Fact10.mp3"};

void setup() {
  size(200, 200, P3D);
  minim = new Minim(this);
    player= new AudioPlayer[10];

  for (int i=0; i<SONGS.length; i++) {
    player[i] = minim.loadFile(SONGS[i]);
  }
}

void draw() {
  background(0);
}

void mousePressed() {

  if(player.isPlaying()==false){
  }

  int v=int(random(SONGS.length));
  player[v].rewind();
  player[v].play();
