Did anyone say *random* noise? :-)
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."
