Lucifer is Dev's sixth collaboration with Mohanlal, and first with Prithviraj as a director. The film's soundtrack consists of five tracks from Malayalam, Hindi and English languages. Usha Uthup was announced to perform the titular song deciphered as the "L Anthem" which was confirmed by the scriptwriter Murali Gopy who shared a Facebook post featuring him Prithviraj, Dev with Uthup and her family.[1][2] Gopy described that the team "have always been great admirers of the way she delivers a song, in a way only she can. So, it was a great thing for Raju, Deepak and me, when Usha Didi agreed to sing a song for Lucifer".[1] Uthup performed the Malayalam version of the same track under the title "Empuraane" penned by Gopy.[2]
Jyotsna Radhakrishnan performed the item number "Raftaara" featuring Waluscha De Sousa that appears in the pre-climax scene.[3] The producers wanted playback singers from the Hindi film industry to perform the track. Dev approached Jyotsna to perform a rough version, and when she performed it, Prithviraj and Gopy liked the track and finalized on her vocals. She described numerous challenges on performing the song in Hindi as "it is a great responsibility to show justice to the language by emulating the right pronunciation". Tanishk Nabar wrote the song after multiple revisions who was satisfied with Jyotsna's rendition.[4]
Dev re-arranged and programmed the patriotic song "Varika Varika Sahajare", originally composed by G. Devarajan and written by Amsi Narayanapilla during the Salt March in 1930s.[5] This version was sung by Gopy.[5][6] The film's original score and songs were recorded at Dev's Wonderland studio in Kochi and Sound Tech in Chennai, with Arjun Muralidharan being the recording engineer and the album was mixed by Shadab Rayeen at New Edge Studios in Mumbai, and mastered by Gethin John and Donal Whelan at Haford Mastering in London.[7]

Critics highlighted the background score being overused and felt repetitive, although the songs were categorised as decent. S. Sethuraman of Film Companion South felt that the music being "jarring" and described it as a "letdown".[11] Sowmya Rajendran of The News Minute felt it as "loud" and "intruding".[12] Sanjith Sidhardhan of The Times of India wrote "Deepak Dev's music could very well be another character in the film, entering the fray and heightening the thrill element at places. However, overuse of the background score becomes jarring at times too and takes away from the viewing experience."[13] Gautham S. of Deccan Chronicle however said that the music complimented the "mass feel of the film".[14]
While the song "Raftaara" was praised by listeners, critics felt that the song being "misplaced" and "poorly choreographed".[11] Devika K. of The Week felt the visual depiction of the song being problematic as certain parts of the song were picturized on the dancer's (de Sousa) body parts blatantly describing the purpose of female objectification contrast to the film's themes.[15]
