Presently I am on hold with my health insurance and what I’m wondering is…who comes up with music you listen to while on hold?

I’ve determined that most of the time it is either classical or jazz music. My health insurance is going with the jazz route and I have presently listened to the same minute and a half clip approximately ten times, each time punctuated by a note at the end to “please keep holding, a customer service representative will be ready to assist you shortly.”

Now I want to know: was there a study done that showed that people will be much happier if they listen to…
