It seems that everywhere you turn, Jay-Z's ode to New York, 'Empire State of Mind,' is being played at top volume, not just by fans but also by Jay-Z himself. The rap star performed it with Alicia Keys at Game 2 of the World Series at Yankee Stadium last month, and used it to close out the NYC-based MTV Video Music Awards. What's more, Bono introduced him as "the Mayor of New York" when he performed at U2's Berlin Wall concert last week.

Could it be that Jay-Z is angling to displace Frank Sinatra's famous song 'New York, New York' with his own 'Empire' as the anthem of the Big Apple? The rapper has long compared himself to Ol' Blue Eyes and makes some boastful claims in the song, which appears on his latest album 'The Blueprint 3'.

"I'm the new Sinatra," he raps, "and since I made it here I can make it anywhere."
