It’s here (or its supposed to be but the link is fail, try here) but why even do it to yourself. Listen to the original , The Realest, with Kool G. Rap. Ok, it’s not the “same” song but c’mon now, that sample was ridiculous when it dropped. I think it was credited to Alchemist., Back At You. Peace to Dj Ian Head for pointing out The Realest samples a different song by Ecstasy, Passion & Pain whereas the Wax Museum/Back At You use Isaac Hayes’ Bumpy’s Lament.
