Background Music

I was in a taxi yesterday afternoon on the way downtown to meet a friend for supper.  The radio was on, and I was just half listening.  But during the commercial breaks, my ears locked in to the background music of some of the ads.  For one of them, it was "Jingle Bells."  For another it was "The  Hallelujah Chorus."  Another one was playing Auld Lang Syne (is that how you spell it?). I chuckled and was reminded of an ad campaign by Air China about 10 years ago when some flunky in their marketing department had chosen the Abba song "Take a Chance on Me" as the background music.
