Jay-Z made his way around NYC Monday, stopping by The Late Show with David Letterman before partying at Butter. As the cast of American Gangster is premiering their buzz-heavy movie around the country, Jay is promoting the new album he wrote inspired by the film. While I can't wait to hear that album in its entirety, Buzz has an awesome taste of the movie's official soundtrack including the catchy song from the previews.
