Why most love songs are like 'sad song'?

I guess because although falling in love it wonderful, falling out of love is more emotional and thus more requiring an expression. Music is so much a tool of expressing our emotions that pain, heart-ache and the unrequited love stories of our hearts just demand a song.

Because love can be sad and it's good to know that others feel the same as you .

Because a true love is always a failure and some men don't realize 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.
