That is a tough question for me to answer, but I will do my best. I would buy the most influential albums of a particular genre that you enjoy listening to. Albums that either represent the origins of the genre or reinvented it.
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.
