10. Lyor Cohen
The Gig: N/A
As the only person on this list who currently doesn't have a job—or a job that anyone really knows all that much about quite yet—Lyor's likely one of the most powerful "unemployed" persons on the planet. After exiting as the Chairman/CEO of Recorded Music for Warner Music Group last September, rumors spread as to what the original Tall Israeli's next move would be. Is he forming a management company with former Murder Inc. capo Irv Gotti to guide the careers of Kanye West and Drake? Is he getting into the content-creation game on an international level? Boasting over 30 years of wins with names from Run-DMC to Jay-Z in his resume, Cohen's power is undeniable for 2013. This is a man who puts all of his chips on the table, and wins. Expect nothing less.
