Your question and statement are the most profound things i've read in 56 years of living.
They weren't great musicians but remember there was no technology back then, recording was 2 track mono and 4 track stereo, no special effects at all apart from a little echo and reverb, they sang live through standard PA systems, no back tracks or autotune, if Justin or 1D did that they would definably sound crap.
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.
