Lucky Number is the fourth studio album by Taiwanese singer Jolin Tsai. It was released on 7 July 2001, by Universal Music Taiwan. Tsai tinkered again with her style for the album, but the downturn in her fortune continued from her last album, Show Your Love (2000). In June 2001, Tsai recorded the Mandarin version of "Where the Dream Takes You", the theme song of the 2001 Disney science fiction film, Atlantis: The Lost Empire, and it was included on the pre-order edition of the album. Just after the released of the album, Tsai's music career came to a halt due to the conflict with her management company of the time, D Sound. The album did not manage to bring her back to the previous popularity she enjoyed, with only more than 150,000 copies sold in Taiwan alone, and made her the nineteenth best-selling singer of the year in Taiwan. The fourth track, "If You Don't Want to", reached number 94 on the Hit FM Top 100 Singles of the Year.
