"This Is It," the title track from the new film "Michael Jackson's This Is It," by Michael himself (with his brothers singing background) will be released on October 12th. It will be the lead single off the movie's two-disc soundtrack of music inspired by the film, which is due October 27th. Two versions of the song will be included on the soundtrack's first disc, which will have the studio versions of Michael's hits in the order in which they are featured in the film. The second disc will include "previously unreleased versions of more Jackson hits" in addition to the previously unheard spoken word poem "Planet Earth." It'll sure be interesting to see what the tracklisting looks like for this. Fingers crossed, though I doubt there will be any more "new" Michael material on the soundtrack, but just to hear "This Is It," which was surely recorded for use in his London concerts, should be incredible. "Michael Jackson's This Is It" will hit theaters for a two-week engagement on Wednesday, October 28th.
