I don't know anything about audio processing, etc... But from what I 
understand isn't white noise just random particles from space, if so 
wouldn't the entropy of the static be quite high (ie random), where as the 
entropy for music, or other structured sounds be low?

Maybe I'm just wrong :) but I find this discussion interesting.
