Recording services can provide a dramatic improvement to your company image by offering your callers on hold messages that convey important facts about your business, including operating hours and featured products. Using on hold messages gives businesses in right throughout Australia a valuable opportunity to communicate with clients and has the added benefit of reducing dropped call rates.
Hold music is part of a good customer service model, demonstrating to callers that you care about making their wait a positive experience. It boosts your professional image and increases credibility, particularly when using custom messages …

You will most likely run into the typical Stalingrad-esque repeating messages that state how important your call is to the business. It is only slightly less annoying to have some form of default music that plays on a loop, and gives you the virtual experience of being stuck in an elevator, listening to muzak ad infinitum.
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.
