I know, from reading Wikipedia, that the Muzak Corporation has changed, and I don't wish to malign its present practices.
But, years ago, I worked at a couple of places with the old fashioned Muzak - which was mostly upbeat instrumental versions of pop standards. It was sold as a kind of emotional programming for a firm's office workers. What I disliked was that the performances sounded oddly lacking in personality. Oh - and I also disliked the fact that the tape looped at least once during an 8 hour shift.
Was designed to hack
Positive thoughts inside your soul.
That, at least, was the goal.
I felt it as an attack.
My mind had music already,
In the background, pulsing steady.
And their product drowned
That inner sound.
