but do they actually know what it means? It's not a generic term for any kind of commercial music, as so many people seem to believe. It's a specific company, which does a specific thing, which is distribute music to stores to play on the PA system and soothe customers. Did you know it started in the 1930's? History can be found here.
A lot of people like to make themselves feel good about themselves by complaining about Muzak, even though often they're not even talking about Muzak, they're talking about music in TV commercials or other commercial things. If you're going to get on your high horse, at least make sure its feet are planted squarely in the truth.
I wish people here in this room and everywhere else in the world would please just stop making so much NOISE.
