I picked up this copy of Muzak, Music of the 80s, at Half Price Books.

Ad copy from the back cover:
"From the top of the international charts to the catchiest of motion picture and Broadway tines- this is Music by MUZAK. Each side of this record is a demonstration of a unique MUZAK programming concept which we define as "Stimulus Progression".

"MUZAK programming creates an environment that surrounds, pleases, stimulates. An environment that helps people cope with pressures of noise, stress, boredom, and fatigue. An environment for people in offices, banks, industrial plants, stores, hospitals, and commercial establishments."

The best part is the graph that displays Stimulus Progression rising with each song played. I'll admit that, by Arthur's Theme, I started to feel a little better.
