Is 'Empire State of Mind' the new 'New York, New York'?

It has been nearly impossible lately to surf the radio without hearing Jay-Z rapping about his gritty-to-glamorous ascent in the big city as Alicia Keys swoons about the "concrete jungle where dreams are made of ..."

The song "Empire State of Mind" was the biggest hit at Yankee Stadium this fall, and then, just days before Jay-Z turned 40, it gave the rap legend his first No. 1 single on the Billboard Hot 100 list. And if it wasn't already ubiquitous, its beat blaring from the radio in almost every corner store, last month Keys issued her own version on her new album and has been regularly performing this salute to the aspirations of native New Yorkers.
