Hmm, I don't hear any popping when I play it. My best guess is that you're experiencing buffer underrun. To remedy this, increase the buffer length. I'm guessing you have a line of code that looks something like this:
new AutoAudioPlayer(null,44100,4000,1050,new Organya("moondust.org","wave100",1)).start();
In this case, 4000 is the buffer length. Try making it bigger, maybe 8000.
edit: the org itself was really cool
though I didn't recognize it.
