The release of this album marked the beginning of A New Day..., Dion's five year concert arrangement in the Colosseum at Caesars Palace in Las Vegas. "I Drove All Night" was chosen as the leadoff single. The original cover version of this song was recorded by Cyndi Lauper in 1989. A version by Roy Orbison, of whom the song was originally aimed, was aired in 1992. Dion's recording became a hit, reaching number 1 in Canada, Belgium and Sweden. Although "Have You Ever Been in Love" was already featured on Dion's previous album A New Day Has Come, it was released as the second single from One Heart in the United States and third in selected countries. The title track promoted the album as the second single outside the United States. There were also two radio releases at the end of 2003: "Stand by Your Side" (United States) and "Faith" (Canada). A song called "Reveal" was written by Cathy Dennis who also wrote "Toxic" for Britney Spears and "Can't Get You out of My Head" for Kylie Minogue among others. "Sorry for Love (2003 version)" was actually an original version of the song. The dance version was released a year earlier on A New Day Has Come. Already available on the A New Day Has Come 2002 special limited edition, "Coulda Woulda Shoulda" was included also here. The last track on the album, called "Je t'aime encore" was also recorded in French (under the slightly different title "Et je t'aime encore") and included on Céline Dion's next album 1 fille & 4 types.
