To sing or not to sing. That is the question.

I was watching a short commercial showing a singer on one of those singing contest shows.  I just don't comprehend the new way (to me) of singing.  Obviously its popular but not my cup of tea.  (I know, I'm showing my age).  Kate Smith, Perry Como, where are you?   I am convinced, by observation, that many of these vocalist, while performing,  are trying to show that they can A.,  have a baby or B.,  pass a kidney stone while standing and bending forward............marge
