After becoming a full-blown superstar whose entire life was different in every way, J. Lo was still trying to convince us she was "real" and still the same old girl from the block. What better way to connect to her roots musically than to put on for her hometown with the greatest Bronx anthem ever put to wax, BDP's "South Bronx"? That's only part of the song, though. The core of the instrumental is culled from the Beatnuts' "Watch Out Now," for a double dose of hip-hop homage. —Insanul Ahmed
