Word up on Madison Ave is I'm a cash cow

from Jay-Z – "Grammy Family" Freestyle Lyrics on Rap Genius

New York City’s Madison Avenue is the traditional home of the advertising business. The term “Madison Avenue” is often used interchangeably for the advertising business as a whole. Hov says “up” to contrast its Midtown location with Wall Street (mentioned below), which is on the southern tip of Manhattan (“up” is north and “down” is south in NYC parlance)
