Complete Best was released a few days before Dion's sold-out concerts in Japan, which were part of the
Taking Chances World Tour. The compilation includes "
To Love You More", originally released in October 1995, which became Dion's biggest hit in Japan, topping the singles chart for four weeks and selling 1.5 million copies. It also includes two other singles exclusive to Japan: "
The Power of the Dream" and "
Be the Man", as well as many of Dion's other hits. The new single, "
A World to Believe In" (U.S.A. mix), was included as the first track of the compilation. Recorded as an English-Japanese duet with
Yuna Ito, the song was released in January 2008 and peaked at number eight on the
Oricon Singles Chart. It was Dion's first appearance on the chart since "To Love You More" (dance mixes) entered it in April 1999. The duet was not included on Dion's previous album,
Taking Chances, which contains the original English solo version of the song. In October 2008, another greatest hits album was released internationally, titled
My Love: Essential Collection. Because
Complete Best had been released recently, this compilation was not issued in Japan. However, new unreleased tracks from
My Love: Essential Collection were included on the CD single
A World to Believe In: Himiko Fantasia, released in Japan at the same time. On 22 July 2009, the album was reissued in Blu-spec CD format in Japan. == Commercial performance ==
