Jackson on path to sixth No. 1 album

'This Is It' may sell 300,000 copies by Sunday night

As Michael Jackson's movie "This Is It" is about to open in theaters, the film's companion album of the same name is already doing brisk business.

Industry prognosticators suggest that the Epic Records set -- which was released Monday -- could shift 300,000 copies by week's end on Sunday night.

Depending on how much the movie's opening impacts the album's sales through the course of the week, the set could post a higher figure -- perhaps 350,000 copies.

With numbers like that, it would seem like Jackson will be a sure thing for the No. 1 slot next week on the Billboard 200 albums chart. If the King of Pop hits No. 1, it will mark his sixth chart-topper, following "Thriller," "Bad," "Dangerous," "HIStory" and "Invincible."

Jackson already owns the No. 1 selling album of the 2009 calendar year with "Number Ones" -- 2 million sold this year and counting. Additionally, his "Thriller" is the year's 11th best-seller (1.1 million) and "The Essential Michael Jackson" is the 15th biggest (986,000).

The "This Is It" album contains 14 studio recordings of Jackson's hits like "Billie Jean" and "Beat It" and two versions of the from-the-vaults title track, which plays over the film's end credits. It also includes three demo recordings and a spoken word poem titled "Planet Earth."
