Although his Blueprint 3 album is not due until later this year, he's still a power player, according to The Source magazine's annual "Power 30" list.

The long-running hip-hop magazine will place Jay atop their annual list this year, when the magazine drops its new issue later this month.

He's the frontrunner, said the mag, because he's an industry leader and a top businessman, boasting a portfolio that includes ventures with Live Nation, Rocawear, and a small stake ownership -- along with a group of investors -- in the NBA franchise, the New Jersey Nets.

Other names on the list include Lil Wayne, Diddy, 50 Cent, Snoop Dogg, Kimora Lee Simmons, and T-Pain, among others.

Barack Obama (because of his influence on the new hip-hop generation) and the Black Eyed Peas' Will.i.an are also named as "Power 30" honorees.

"The Black Eyed Peas is like one of the biggest groups on the planet. We go out to Brazil, you know, a million, two hundred thousand people is at our concert," Will explained to the mag.

The "Power 30" issue features a coverstory from T.I. and his Grand Hustle crew, and what the rapper's hustle will be post-incarceration.

The issue hits newsstand June 16th.
