Jay-Z over two decades is known to be one of the rare emcees who don’t write their lyrics, but still recite them with fervor when in the booth.
Even in the song “Welcome To New York City” feat. Cam’Ron, Jay-Z spits, “..the hand that write checks to be the hand that don’t write/ I go off the head when I’m scrambling on the mic..”
According to his most recent interview on ‘HBO’s The Shop’ with NBA great Lebron James and Maverick Carter, Jigga says that he used to forget his rhymes when he hit stages for live performances.
When Lebron asked the cultural mogul whether or not artists “zone out” during their live performances, to which Jay-Z responded, “In the beginning, I used to get on the stage and just forget all my lyrics.”
