To the extent I ever thought about it, I always supposed that music in stores was intended to emphasize the mood to shop, to make you more willing to part with your cash.
But now I am forced to reevaluate this notion.
I was in my friendly neighborhood Superfresh the other day ("Your Supermarket of Choice!" Whatever the Hell that means) when I began tuning into to the music droning on over my head. Some inoffensive Billy Joel - "Captain Jack" specifically. Oh, sure, the content is a little heavy (an anti-heroin song, or whatever), but it is perfect, hypnotically bland music by which to buy groceries.
But then something weird happened. The next song featured a familiar buzz-saw guitar intro and the unmistakable mad howling laugh of the singer. I listened more closely.
Yes. "Crazy Train" by Ozzy Osbourne.
I wonder what retail consultant looked at the playlist and said "Yes, Sir,Ozzy Osbourne. THAT will make people in South Philly buy more bread and milk."
