What is a good topic for a rap song?

Easy things to write about: Well you could talk about drugs and the influence they have on teens. You could rap about breast cancer and how many women and Men die from it. Or you could be like most common day rappers and rap about how much money they have.

You could rap about the environement and how people should be more aware, may sound cheesy but I sware the world needs this. if we keep going on the way we do the main water source of the entire world won’t exist anymore which is the himalayas- the netherlands will disappear forever - and much worse. the world is dying. rap about something meaningful- I have always believed that rap was a way of sending out a message, more than just singing.

I agree w/ drunky on that first sentence, people like and need to get answers!;)
