It was written by John Ryan, Ross Golan, Jacob Kasher Hindlin and Ian Kirkpatrick, and produced by the American production duo Afterhrs under the direction by J Kash.
[2] Dion recorded five new songs for the film, including "Love Again" released on 13 April 2023, her first new music in four years and since she revealed in December 2022 that she has been struggling with stiff-person syndrome.
[5] Larisha Paul from Rolling Stone gave the song a positive review and called it a "fittingly an alternate universe version of "My Heart Will Go On".
[7] She added that the chorus of "I'll Be", which promises "No, you won't be alone through the highs and the lows/You know you got me/Wherever you go", feels like a repackaging of "Near, far, wherever you are/I believe that the heart does go on", if only Titanic actually followed the story of a woman grieving her fiancé and a journalist assigned to profile Celine Dion and not two star-crossed lovers on a literal sinking ship.
[11] The lyric video with clips from the film alongside photos and messages from fans around the world was released on YouTube on 5 May 2023.
