DJ Shadow had a drumline sample, on one of his sets, I thought it was Brainfreeze, but I'm not sure someone know?

No, well it really depends who the rapper is.

Rap can be a bad influence. Even the greats like Biggie and Tupac talk about smoking blunts and committing crimes in their raps. But rap can only be a bad influence if you let it influence you.

If you don't let it influence you though, there's really no point in listening to 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.
