Producer Rodney 'Darkchild' Jerkins has announced he's setting to work on unreleased Michael Jackson songs.

The producer worked on Jackson's 2001 album Invincible.

He told VladTV: 't's definitely going to come, but it takes time. You got to do a lot of the red tape but there's definitely going to be an unreleased Michael Jackson [album]. There's definitely going to be stuff to come and hopefully I'll be a part of that.'

Jackson was busying himself with a comeback album at the time of his death, working with producers Ne-Yo, Akon and will.i.am as well as rumoured collaborations with Kanye West, T-Pain and Chris Brown.

There is a presumption that unreleased Jackson material might date back decades, as every album would've had offcuts and b-sides that never made it out.

In March this year, Sony signed a new deal with Jackson's estate to release ten albums of unreleased material and new collections of previously released work.

The first album is reportedly due for a November 2010 release, with the final album due out in 2017.

It's the most expensive music contract of all time, Jackson's estate earning $250 million up front as well as a slice of forthcoming royalties.

Jackson's future output is sure to overwhelm the material he released when he was alive.
