My husband explained to me at some point (during our brief history) that there is a company that compiles music for stores worldwide. It is called Muzak. When you're in the GAP, you hear GAP muzak or, rather, music that is appropriate for the GAP brand. Actually, I don't know for sure that the GAP uses muzak, but I'm willing to bet it does.
According to Muzak's website, it "creates experiences for the world’s most admired brands." Wow. Don't you wish you had thought of it first?
I like to think of what muzak would be playing in the background of my life.
