A year ago this month, Joie Manda was appointed Def Jam President. But today, he announced his resignation and new position as President of Urban Music at Interscope Records

No word as to his successor, but in statement he said the following.
“Despite having to move back to Los Angeles for personal reasons, I am truly grateful to Barry, John and Jimmy Iovine (Chairman & CEO, Interscope Geffen A&M) for this exciting new opportunity. I’ve learned a lot from Barry in the last year and am very appreciative of everything he has done for me. I am now looking forward to being part of the Interscope family, a company uniquely positioned for success despite this challenging marketplace.”
