he definatly has way more lyrical skills that most of the people out there, the fact he's been "mainstream" lately doesnt reflect his lyrical ability at all, it reflects his marketing skills. and thers a difference between being 'mainstream" and "pop"(50 cent, for example.) mainstream rappers simply get attention from a large amount of people, pop rappers make songs specifically for radio and the general public, and usually the music put out by a pop rapper is garbage. I believe Nas can lyrically slaughter almost any artist, and to me that sets him above the general rap community.
