In November 2014, A. R. Rahman was announced as the film soundtrack and score composer, working with Suriya for the third time after Aayutha Ezhuthu and Sillunu Oru Kaadhal.[3] Rahman had a six-hour script narration session with Suriya and Vikram Kumar before signing the project.[4] Recording of the track "Punnagaye" written by lyricist Vairamuthu was completed by February 2015.[5] In an interview with The Hindu, Suriya told that the recording of one more track was completed by September 2015.[6] According to lyricist Madhan Karky, for the track "Naan Un":[7] Rahman was trying out a tune on his piano and Karky was writing the lyrics while listening to him. He wrote a line in Tamil, "Undhan Azhagil Iraivanai Kaankiraen" that translates to, "In Your Beauty, I See God." An inspiration before composing tunes, Rahman had read the same line from the Prophetic books before composing that track.[8] However, the track was initially composed for some other film.[8] Later, it was reworked to suit the film soundtrack.[8] An additional composition written by Madhan Karky titled, "Dangerskku Hi5 Podu, Daredevilkku Vaanam Podu." was as an intro song only in the film score.[9] However, the track was released as a bonus single under the title "24 Carat" on 19 May 2016.[10]
