Muzak changed their tune from "background music" to what they branded initially as "foreground music" when they switched from the elevator music (known as environmental) to original artist offerings. After about a decade of calling it foreground music they again rebranded, changed the logo, moved their headquarters to Charlotte and started calling it "Audio Architecture" (the entire slogan was "Creating experiences with Audio Architecture). I should know, I worked for them for 7 years. Actually a pretty cool company all things considered. When I left, the "environmental" music was less than 2% of the business.
