2019 soundtrack album by Vishal–Shekhar, Sanchit Balhara and Ankit Balhara
War's soundtrack was preceded with the first single "Ghungroo" released on 5 September 2019. It was written by Kumaar, and sung by Arijit Singh and Shilpa Rao. The song was choreographed by Bosco–Caesar and Tushar Kalia, which was shot at the Positano beach in Italy and Amalfi Coast. The second single "Jai Jai Shivshankar" was released on 21 September. It was sung by Vishal Dadlani and Benny Dayal, and choreographed by Bosco–Caesar; set against the backdrop of Holi celebrations, the song featured Roshan and Shroff dancing at the festival. The hook of the song is inspired from the eponymous song from Aap Ki Kasam (1974). The soundtrack was released by YRF Music on 27 September.
Debarati S Sen of The Times of India reviewed the song "Jai Jai Shivshankar" and stated that the duo "have woven the feel of unfettered revelry in the soundscape and that comes alive in the dance sequence"; regarding "Ghungroo", she described the song as a "uber-modern twist" of the ghazal number "Ghungroo Toot Gaye" from Param Dharam (1987) and added that "electronic elements have been used generously in the soundscape which give the party track, a lazy yet groovy vibe". Joginder Tuteja of Bollywood Hungama stated that the soundtrack "adds on further punch".
Pratishruti Ganguly from Firstpost described that the songs, are "catchy in their own right, but lack repeat value"; she was more critical of the album's length, adding "Had the album of War offered a longer selection, it probably would have been relatively easier to decide if the soundtrack warrants repeat listens." Anupama Chopra of Film Companion criticised the songs being "force-fitted" and added that "the background music by Sanchit Balhara and Ankit Balhara has more impact than the two songs by Vishal–Shekhar". Swarup Chakravarthy of BollySpice wrote "the album never really gets going and definitely has no flow about it". Nairita Mukherjee of India Today called the music as "strictly passable". Hanna Rachel Abraham of The Week complimented the music as "decent" but "the songs are abruptly placed and add nothing to the story whatsoever except seeing Hrithik Roshan dance again".
