   FWIW (probably nothing to some of these newsgroups), I (out of
curiosity) just opened an MP3 file as a raw 16/44 stereo PCM file in
Cool Edit and played it. It sounds like noise with no discernable
'pattern' or 'beat' that would indicate blocks to me. So it's for at
least some practical purposes it's "random enough."
