Glen Brunman also stated that the soundtrack album was supposed to be 'No song, no Céline'. James Cameron felt obligated to include a theme song to promote the film. Franglen had worked with Dion for several years on many of her major hits to date. Horner showed the piano sketch to Simon Franglen, who was working with him on electronic textures and synthesizers for the film score. When Dion originally heard the song, she did not want to record it as she felt she was pushing her luck by singing another film theme song after ' Beauty and the Beast' and ' Because You Loved Me'. Director James Cameron did not want such a song, but Will Jennings went ahead anyway and wrote the lyrics. Lyricist Will Jennings was hired, who wrote the lyrics 'from the point of view of a person of a great age looking back so many years'. He then wanted to prepare a full vocal version of it, to use during the film's end credits. James Horner had originally composed the music for the song as an instrumental motif which he used in several scenes during Titanic. Dion performed the song to honour the 20th anniversary of the film at the 2017 Billboard Music Awards on May 21, 2017. The music video was directed by Bille Woodruff and released at the end of 1997. It was also included in the list of Songs of the Century by the Recording Industry Association of America and the National Endowment for the Arts. It also was the world's best selling single of 1998. With worldwide sales estimated at over 18 million copies, it is the second best-selling physical single by a woman in music history, and one of the best-selling physical singles of all time.

'My Heart Will Go On' is considered to be Dion's signature song. Outside Canada, 'My Heart Will Go On' became a global hit, topping the charts in over twenty countries, including Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Italy, the Netherlands, Norway, the Republic of Ireland, Spain, Sweden, Switzerland, the United Kingdom, and the United States. Released as a single from Dion's fifth English-language studio album, Let's Talk About Love (1997), and the film's soundtrack, the love power ballad peaked at the top of the RPM Top Singles Chart. The song's music was composed by James Horner, its lyrics were written by Will Jennings, while the production was handled by Walter Afanasieff, Horner and Simon Franglen.

The song serves as the main soundtrack to James Cameron's blockbuster film Titanic, based on an account of the transatlantic ocean liner of the same name which sank in 1912 after colliding with an iceberg in the North Atlantic Ocean. ' My Heart Will Go On' is a song recorded by Canadian singer Celine Dion.
