Okay so are you going to make the argument that "rappers" like Soulja Boy, Paul Wall, Nelly and other mainstream manure should have been included then random scrub forefather with a hit?
I'll take a guy talks about something silly or simple over bitches, 40's, grills, and weed. Could they have thrown in a little more of the educated, newer stuff thats a tad underground. Sure, but I'd rather take that then listening to some retard tell me how Ludacris is nasty, when in reality, rappers like that come up with computer generated club banger beats and repeat words until there is some sort of catchy vocal melody.
I do agree with you that acts like Roxanne and crap, shouldn't even be discussed with such a list. But I rather that then someone lying to me and telling the fans that modern hip hop is gold. Again I am pretty knew to the genre, I'm not going to lie. I am no hip hop expert, but every time I hear a dirty south rap song (for instance) I want to kill the person who created it.
