Jackson's new single 'not a fake'

Michael Jackson’s record label today insisted his new posthumous single was genuine in the face of family claims that the voice on it was someone else.

“When I heard these songs, my heart cried hearing Michael again in good spirits. The vocals sounded very polished, very on key and processed. I have no doubts that these are Michael’s vocals,” Jackson’s long-time producer, Teddy Riley, said .
