Hmm, indeed. I played it on my phone (HTC Typhoon branded as Orange C500), and
heard a fairly raspy buzzing sound, with the odd burst of static. I played it
on my laptop's speakers (Dell Inspiron 8600), and heard nothing, ever at max
volume. Then I plugged in my portable stereo headphones (Sennheiser PX100s),
and heard a high-pitched sound that practically made my eyes water.
So, it seems like, for different reasons, neither my laptop nor phone speakers are up
to the job of playing this sound, but given decent headphones, I can still hear it.
So perhaps you can blame your external audio equipment. :-)
