How is Hip-Hop killed? Lol… By the way, Rap is not the entire genre of Hip-Hop by the way.
In either case, Dirty South rap has brought more attention to rap and made it more popular with the general public at the expense of originality and quality.
Its safe to say that Rap is in dire need of reinvention, but I wouldn’t say its killed because Hip-Hop has more listeners and fans than ever.
