Taking on Ringback tones

I get that the appeal to hearing JayZ or Carrie Underwood when calling
a teenager instead of the standard ringing noise but I am not sure I
get the appeal for an adult. Every time I call my Korean real estate
broker I hear Mozart which might sound more pleasant but truthfully
just sounds unprofessionally. I get kids wanting these things and
there are probably places around the world where they are considered
OK but I am glad to not be 15 anymore and also more than happy to not
live in Sri Lanka or Kuala Lumpur or Seoul because if I had to put up
with this everytime I called somebody o'd throws IPhone into the south
china sea because these things are beyond annoying
