I don't think I have to explain what a freestyle is but if I have to... Freestyling, in its original form, with reference to rap is the art to magically recite rhymes that you the artist have never recited or written before in your life. Making use of your immediate surroundings - though not limited to it. Its impromptu, random and basically you just go. The key though is to make sense. Supernatural the emcee is one of the most accurate freestylers of our time. Bless!
