Michael Jackson's This is it song goes online October 12

Late pop legend Michael Jackson's first posthumously released new track This is it will be available to download at the stroke of midnight on October 12, according to Sony Music.

Sony will unleash the previously unheard songs, which feature backing vocals from Jackson's brothers, online Monday and the track will then appear on a new two-disc album of the same name, set to go on sale later this month to coincide with the global premiere of the King of Pop's This Is It documentary, about his ill-fated comeback concerts, reports contactmusic.com.

"This song only defines, once again, what the world already knows that Michael is one of god's greatest gifts," said album co-producer John McClain.

Jackson died on June 25. His death has since been ruled a homicide.
