Just rediscovered this gem a couple days ago:
All the verses are so crazy (Chubb Rock's is my favorite), and that beat... god, that beat is amazing. Easily one of DJ Premier's best.
Really, if I could add just a single song to GTA IV's radio, it would be this one. Yeah they name-drop Brooklyn all over it (and name-dropping real locations in songs has never been a dealbreaker for GTA soundtracks anyway. "California Soul", anyone?), but this would fit that LC atmosphere like a glove.
