If it is a genre, hold music, it's fair to say, is a troubled one with few hits. It's not really meant to be loved or even listened to — it's meant to communicate something specific: Don't hang up. (Cornell makes this plea specifically at the end of his song.) Silence is believed to be a death knell for phone calls — people will simply think the line is dead and hang up. This is true even on non-hold calls; it's why phone companies transmit something called a "comfort tone" over phone lines, a barely audible synthetic noise that signals a connection is still there.

Lastly, real-time status updates are a useful way to keep track of your messaging system. With marketing automation, they can be sent to a manager for better decision making. Web-based management portals allow you to see account details as well as past and present on hold productions. This way, you can track the status of a particular customer’s production request, analytics and your on hold messages all in one place.
