"I will not support 'Breaking News' and a few others [off the album] because it simply is not him," Taryll Jackson, son of the singer's brother Tito, wrote on Twitter.
Much of the song features multiple vocal tracks, making it hard to pinpoint where Jackson is, but the opening line has a single, arguably weak and shaky, voice. Listen to It Here
"Everybody wanting a piece of Michael Jackson, reporters stalking the moves of Michael Jackson, just when you thought he was done, he comes to give again," the lyric goes, over a bouncy drum and guitar line.
Without saying which parts of the song he thinks were altered, Taryll reveals he isn't alone in believing something's amiss.
"I KNOW my Uncle's voice and something's seriously wrong when you have immediate FAMILY saying it's not him," he writes, later adding, "Sounding like Michael Jackson and BEING Michael Jackson are two different things."
TJ Jackson, another son of Tito's, calls the track a sham and criticizes Sony for pushing the single, which he claims was not a priority of Michael's.
"There's many MJ vocal impersonators. Some better than others. But there is only ONE Michael Jackson. Deceptively merging shady vocals with MJ samples (from prior MJ records) will never fool me. Why they would ignore the obvious, look the other way and rush a suspicious track that was NEVER on my Uncle's radar is beyond me. I'm disgusted, disappointed and saddened."
Even Jackson's sister, LaToya, has weighed in, telling TMZ, "That doesn't sound like him."
Responding to the controversy, Sony said in its statement that it had "complete confidence in the results of our extensive research, as well as the accounts of those who were in the studio with Michael, that the vocals on the new album are his own."
