Michael Jackson's brother has expressed his anger over new 'Michael' album, claiming that the songs are bogus over Twitter.

In a series of tweets on Twitter today, Randy aknowledged his frustration with record label Sony on their decision to release the album and said that his brother's voice does not feature on every track.

"Me and my nephew were the first to say that it wasn't his voice on some of the tracks. The family and the executors of the estate, Branca and (John) McClain, are not on the same page. We don't see eye to eye," Randy said.

He added: "I heard the music and I immediately said it wasn't his voice. Some of the songs are him, and some aren't. I would bet my life on that."

The new album 'Micheal' due for release next month has already caused disputes amongst Akon and Black Eyed Peas' Will.i.am.
