Why Eminem is the Best on the Top?

This is somehow a question that goes into the minds of the other rappers, WHY HIM?

Obviously he had perfect contents of his rapping performances.
He managed to keep moving forward of his career and, without Dr. Dre that gave him the determination, he would not reach this far
Eminem - Berzerk ( 2013 )
Now that Eminem is back, he is called the " Rap God " from now on after his release of his new album for 2013 to 2014.
His songs were an inspiration of himself and to us the fans of his. He rolled bozo's out of the trucks. He is unstoppable, incredible and forever the best on the TOP of Rapping!
