pop music is simple way to get money with little effort applied at all times since we started recording artists.
Rihanna, Justin Timberlake or Bieber or Beyoncé aren’t any better or worse than Bruce Springsteen, Bon Jovi, Bette Midler or Pat Benatar .
Dean Martin proved to the world that miserable crooner as he was couldn’t be a jazz singer. Barry Manilow also proved that he’s just another miserable microphone dude as well.
Wat else u can expect from pop? It’s cheap to build and bring -- that’s all its purpose for all times and days.
Pop and music are two different meanings where music requires continuous and intensive training and practicing and pop just only needs ’pre-cooked show biz recipe’. As an analogy, you can compare canned food with home made or chef made fresh food.
