According to The Sun, the release of the previously unheard material has been thrown into chaos because the Jackson family believe that several tracks recorded in 2007 do not contain Michael’s vocals.
His children are allegedly being asked if their father was present in New Jersey at the time of the recordings. A forensic audiologist has also been asked to analyse the tracks to determine if they feature the ‘Thriller’ star.
A source said: “With so many rivals wanting control of Michael’s Legacy a new album was never going to be easy. Sony want this ironed out quickly. If they get this out for Christmas it will sell boatloads.”
The report claims that Sony has a £125m deal with Jackson’s estate.SOURCE
