Juxebox play music?

Is there an way to play the music cd's? i have tried this, but with no succes:

Code:java

       for (Player all : Bukkit.getServer().getOnlinePlayers()) {
       //-1258, 14, 1131
       all.getWorld().playEffect(all.getLocation(), Effect.RECORD_PLAY, (byte) 12);
          }
       }
