Pop music is short for "popular music" so anything that is on radio that plays "hits" is "pop" music. In the old days, pop was on AM radio, while FM radio could breanch out and play alternate types of rock music. Pop is somewhat misunderstood though in today's culture.
But yes...it is mainly teen music by vapid artists like Taylor Swift, Ariane Grande or whatever that is considered "pop" right now. And a metal fan is not going to like "pop" music or the Beatles either, because the Beatles, to today's young teens, is old and lame and too "weak" to be rock music or not "pop" enought to twerk to. Lol.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
