This is the UK version of the album King of Pop made to celebrate the king of pop, Michael Jackson’s 50th birthday. The album was officially teased by the Michael Jackson Estate on July 24, 2008, and was originally going to be released on August 25, 2008, but then was released 3 days earlier on August 22. It was a collection of Michael Jackson songs that were released before the release of King of Pop. It included big hits such as “Billie Jean”, “Beat It”, “Thriller”, and “Bad”. It also had remixes of songs such as “Black or White”, which they remixed into “Black or White (The Cilvilles and Cole House/Club Mix)”. It had the track “Thriller Megamix” which faced some backlash as it was meant to be an exclusive track only on the celebration album Thriller 25, meant to celebrate the 25th anniversary of Jackson’s hit album Thriller, which was the best-selling album of all time.
