The Lion King

On November 1, 2017, it was announced that Hans Zimmer, who composed additional music for Favreau's Iron Man, will return to score the film, having previously scored the 1994 animated version. Zimmer initially hesitated in returning to score the remake, stating that "[he has] worked very hard to not ruin things through improvement", however, he ultimately agreed to return after performing the original film's score during a concert, saying that he "suddenly realized what [his] place in this new version was: to try a big experiment and use my band and orchestra, go back to Africa, work with Lebo and the chorus and extraordinary musicians from all over the world, and really make this a performance". Zimmer said that he treated his work on the remake similar to his work on the original, stating that "[He is] doing this strictly for the people for whom it means something. [He is] working [his] musicians to the bone because [he] wants to get that performance. [He wanted] to smell sweat and blood in [the] studio".

On November 28, 2017, it was reported that Elton John had signed onto the project to rework his musical compositions from the original film before his retirement. The following day it was reported that Beyoncé would be assisting John in the reworking of the soundtrack. On February 9, 2018, John reported that he, Tim Rice and Beyoncé would create a new song for the end credits of the film. Later that month, it was announced that four songs from the original film would be included: "Circle of Life", "I Just Can't Wait to Be King", "Hakuna Matata", and "Can You Feel the Love Tonight", the latter being performed by Beyoncé, Glover, Rogen, and Eichner. On February 3, 2019, Skyler Shuler of The DisInsider reported that "Be Prepared" would be featured in the film as well. Favreau said that the experience of "not trying to create new songs but trying to build on what people remember and love about the old ones, has been really fun and formative". The score and the songs in the remake were influenced by the music featured in the Broadway version of The Lion King, as Favreau felt that "[Zimmer and John] really [explored] further what the roots of the music are [in the Broadway show]".

John and Rice wrote a new song for the film's end credits, titled "Never Too Late" and performed by John. The film will also feature a cover of The Token's "The Lion Sleeps Tonight", performed by Rogen and Eichner, in a scene re-creating an scene from the original film which featured the song, as well as the song "He Lives in You" from Rhythm of the Pride Lands and the Broadway production, performed by Lebo M. Pharrell Williams will produce five songs from the film. The soundtrack, featuring Zimmer's score and John and Rice's songs, will be released digitally on July 11, 2019, and physically on July 19, 2019.
