I personally ADORE every single song that scop has made. Try listening to Utakata Dance, Doubutsu Uranai, or Yubikiri for starters. I also love Hachi's songs, like Matryoshka, Wonderland to Hitsuji no Uta, and others.
If you prefer something rock-ish, you could listen to Nashimoto-Ui's songs: Petenshi ga Warau Koro ni, Kutabare PTA, etc. By the way, DECO*27 has some really nice GUMI songs, if you don't mind her voice. Yowamushi Montblanc and Mozaik Role are the best ones, in my opinion.
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.
