*Randy Jackson exploded on Twitter again regarding the posthumous album due next month from his brother.

“Some of the songs are him, and some aren’t.  I would be [sic] my life on that … I know this may seem harsh, but this is the truth, as I know it…,” he tweeted Wednesday night regarding Sony’s “Michael,” to be released Dec. 14.

Although the label and producers who have worked with the King of Pop vouched that the vocals are indeed Michael’s, Randy isn’t buying it.

“But what’s worse then [sic] harsh is that my brother isn’t here, and all these people are more concerned about making money off his death…They could care less about why and how he died, or maybe they already know.”

Randy also claims co-executor John McClain “didn’t care about the quality or how complete the vocals were.”
