Phoenix underground emcee Realistic has linked up with themadbloggers.com, djcosthekid.com, and D&M to bring you the lead single off his upcoming mixtape entitled Greatest Hits. I really hope the world is ready for this kid because he is run away lyricist that has no thoughts of pumping the breaks. Look out for his full project to drop this Tuesday 4-24-12 via TMB, DJCTK, and D&M.
