Pritam composed the musical score in his third collaboration with Saif after Love Aaj Kal (2009) and Agent Vinod (2012). As with his previous films, Pritam would compose the tunes while Irshad Kamil would write the lyrics that match the tune. Five songs for the film had been curated for the film's music, except for "Yaariyan" which had been composed instantaneously.[1]
Vijan considered the film's music and score as the USP of the film.[2] He wanted the songs that relate with the characters and bring out their personalities and traits and seamlessly integrate with the storyline instead of random transitions to the music interrupting the screenplay. He acknowledged that "the songs have been shot entirely from Homi's vision, and the result has been fantastic".[3] According to Pritam, his collaboration with Kamil owed him a lot due to the phonetic quality of the words. He added, "Being a Bengali, my ears are more dependent on the sound of the words rather than their meaning, and Irshad bhai writes words that instantly appeal to my senses".[3]
The soundtrack is heavily influenced by Sufi music. Pritam attributed the lyrics of "Tumhi Ho Bandhu" where its catchy hook line originated as a Sufi tune. However, the underlying theme of the soundtrack had a folksy nature.[3] The song "Yaariyan" drew inspiration from Coldplay's "In My Place" (2002), while Pritam clarified that he used the drum pattern which was common to that track.[3][4] Vijan acquired the rights for the Pakistani Sufi song "Alif Allah" performed and written by Arif Lohar, which was newly arranged by Pritam.[5]
