"This Is It," a new Michael Jackson song, will be released as a single on Oct. 12, according to U.S. media reports Thursday.

The Sony Music Entertainment announced Wednesday that the song, which features backing vocals by Michael's brothers, the Jacksons, will be released in October, adding that a two-disc album will be released internationally on Oct. 26 and in North America the next day.

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

The film, which chronicles Jackson's final days rehearsing for his comeback concerts, will hit theaters on Oct. 28 for a two-week run.

The pop star died June 25 at his rented Holmby Hills mansion in Los Angeles at the age of 50, just days before he was to perform a series of concerts in London.
