Scratch is truly a must, and to tell you the truth, I am hoping The Roots not play with John Mayer. I mean that guy when he sings, makes funny faces. DAMN, why would you want him doing anything with you? Also, I miss the old stuff from The Roots, it was so much more jazzy. I liked Phrenology, but it really had me Wanting MOre!?!?!?! like, phrenology missed Dice, he would have been perfect for some of the harder tracks, like Rock you, he would drop crazy hardcore rhymes about jacking suckas for all they have. Man one of the reasons i fell in love with the music of The Roots was Dice Raw going on and on with his bad ass self.
