Rocko is another label head turned rapper, so some might give him a pass for his selection of beats. However, the rap game doesn't have an affirmative action program for its artists and each must--or should-- get on based on actual skill.
A common misconception divides many of today's Hip Hop fans. On one side of the aisle, there are those who believe that an artist has to be positive in order to be dope; the other side believing that big words and catchy metaphors about the lifestyles of the rich and famous make for a dope MC. The answer lies somewhere in the middle. All "positive" or "conscious" MCs aren't dope and all the dope boys aren't wack. There are plenty of MCs on both sides of the spectrum that are great and others that are great at being terrible.
