The hip-hop magazine says Jay-Z tops the list because he's an industry leader and a top businessman, with his ventures with Live Nation and Rocawear, and his part-ownership of the New Jersey Nets.

Others on the list include Diddy, 50 Cent, Lil Wayne, will.i.am, Snoop Dogg, T-Pain and Kimora Lee Simmons.

President Barack Obama was given top billing on the honorary power list because of his influence on the new hip-hop generation. -- AP
