Michael Jackson's brother wades into 'Michael' album controversy

Michael Jackson's brother Randy has joined the row over the late singer's posthumous album 'Michael'.

Ranting on his Twitter page, Twitter.com/randyjackson8, Randy renewed the family's accusations against Sony Music, claiming the label has not used genuine Michael Jackson vocals on the record.

"Some of the songs are him, and some aren't," he wrote. "I would bet my life on that. I know this may seem harsh, but this is the truth, as I know it."

He added: "But what's worse than harsh is that my brother isn't here, and all these people are more concerned about making money off his death."

His comments come after Sony Music denied the vocals on single 'Breaking News' were not recorded by him. The late singer's nephews TJ and Tarryl accused the label of "deceptively merging shady vocals with MJ samples".

Randy wrote: "Sony has 250 million reasons to convince the public that it is his voice, if you know what I mean. Like [promoter] AEG, they were cutting deals with the estate before I could get my brother in the ground. My brother was a perfectionist, and they are paying no regards to quality."

'Michael' is set for release on December 14.
