In the 60s and 70s, many adults of those generations, thought of
  that music as garbage and regurgitated nonsense. This is
  perfectly normal. I hear the repetition in today's music * but
  there's also innovation here as well. We don't hear most of the
  music of the 60s and 70s * we only hear the good stuff * the
  cream of the crop. In 20 years, most of today's music will be
  forgotten * but there will be a few standouts that will survive.
  And some ppl will long for the good old days of 2015 music.
