Rap music, the ironic business of selling a lifestyle of money, status, women and cocaine to impressionable, which has made successful businessmen out of people like Jay-Z, P. DIddy and others, has often been used as an an example to conduct business. I agree with the idea, as long as you are aiming for misanthropic psychopathy. 

See, I agree that one has to make money. But, there has to be an okay way about this. 'It's only business' is one of the idiotic phrases I have heard in my life. Rap music business lessons.
