My all time favorite has always been "Kokoro" by Kagamine Rin. But after that my favorite Vocaloid is Megurine Luka and my favorite song by her is "Just be Friends". After a while I started searching for some Vocaloid songs (as in a bunch of Vocaloids in one song) and I throughly enjoyed "Alice Human Sacrifice".
As for my favortie duet is "Magnet" by Hatsune Miku & Megurine Luka. But my favorite PV is "Matryoshka" by Gumi and Miku.

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.
