The singer's longtime producer Quincy Jones blasted record bosses at Sony for allowing the perfectionist's unfinished songs to be heard by the public, while members of the Jackson family have raised concerns about the authenticity of the vocals.

He tells TMZ.com, "If Michael was still alive... I don't think the album would be out yet... I'm gonna stick to my old Mike."
