Well that's correct, but I think Brad what you fail to understand, and what many are trying to tell you is that "smooth jazz" / "musak" / elevator "music" is not actually music at all. Just as some might perceive pink noise as simple and annoying low level static (which may be technically accurate) it really drowns out background noise to help one think more clearly... to focus. Musak on the other hand is designed to do the opposite.
Musak while technically may be a form of music, it is designed to dull the senses. It's made to take you from "If you put me on hold again you dumb b***h I'm going to dismantle this f****ng computer with a f****ng sledge hammer." to "Thank you so much for allowing me to ship this machine back to you so that I may be without the use of a computer for at least two weeks. Now you have a good day."
Or to offset the desire to "Rip my boss' f****ng head off and shoot all my coworkers." to "We're throwing a pizza party on Friday, everyone bring pictures of your children because we love them too." by those who spend large amounts of time pushing paper in nondescript office dwellings.
There are actuary tables that guide you in exactly how much "Songbird" (the most potent form of musak) is required to offset any level of outrage. Of course some places need 8-10 hours of musak daily to ease the outrage. But as you see, none of this has anything whatsoever to do with jazz music per se.
So whether you love Gorelick or hate him, it really all depends on what side of the line you call home my friend.
