In typical Throwback Thursday fashionTim Westwood just shared a very rare Mos Def freestyle from 1999. To no surprise, Mos Def, or Yasiin Bey​, completely snaps throughout this five-minute freestyle, which Westwood noted was off the top of the head. Mos spits, "I'm making it right, telephone hotlines with hot rhymes, did the only job one time, it's not written, not rehearsed, still busting the verse." Last month, Westwood also shared a rare Jay Z freestyle from 1999, so maybe this is a trend that will continue.
