With a lot of rappers it's hard to tell if it's written or off the dome. But i know Flip truly freestyled some of his rhymes. But the ones u hear than a few months u hear a recorded version in a whole song u know those ones are written. But a lot of cats so good at making u think they freestyling or don't use pen to pad. Biggie started that now everybody from Jigga to TI to Wayne among others say the same thing. Maybe thats why a lot of music sucks now. Cause of freestyling or writing in ur brain.
