The first 43 seconds of Michael Jackson’s long-awaited “This is It” song has leaked before tonight’s official debut at midnight EST.

The song, which TMZ released ahead of schedule, will be a part of the two-disc album of music inspired from the film “This Is It,” which opens October 28.

What do you guys think of the song? Will it give MJ a new number one?
