I think more rappers need to take notes from E-40. The man is well spoken. He let's it be felt he's humble, yet let's it be known he's a pioneer & one of the best in the game. Without making it sound like too much, or bragging like he's untouchable. Or trying too hard to shove his music down your throat.
I have to respect the man one everything. For somebody to be in the game that long, accomplish what he's accomplished and still be a regular guy like that? That reflects he hasn't forgotten where he's come from.
