Michael Jackson is on track to score his sixth No. 1 on the U.S. pop chart next week with the companion album for his new concert movie This Is It.

Industry prognosticators suggest the album -- which was released on Monday -- could shift between 300,000 and 350,000 copies by Sunday night. Sales data for the week will be released next Wednesday by tracking firm Nielsen SoundScan.

Jackson already owns the year's best-selling album with his 2004 hits package Number Ones -- 2 million and counting. Additionally, his 1983 blockbuster Thriller is the year's 11th best-seller (1.1 million) and 2005's The Essential Michael Jackson is the 15th biggest (986,000).

Thriller marked his first No. 1. The follow-ups, Bad, Dangerous, HIStory and Invincible, also hit the top.

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. The film opens worldwide on Wednesday.
