Raanjhanaa is the soundtrack album, composed by A. R. Rahman of the 2013 Hindi film of the same name, directed by Anand L. Rai and starring Dhanush, Sonam Kapoor and Abhay Deol in the lead roles. The film is produced by Krishika Lulla under the banner Eros International. The lyrics of the original version were written by Irshad Kamil whereas the Tamil lyrics were written by poet Vairamuthu. The soundtrack album features nine original tracks. The music of the original version of the soundtrack was released on the co-branded record labels Sony Music and Eros Music on 11 June 2013 and the Tamil version on 24 June 2013.

In June 2012, A. R. Rahman was signed on to compose songs and the background score. He agreed to compose after the script was re-written entirely in English by the director and the former kept the script personally. The composition of the song "Banarasiya" was ready by September 2012 but was not recorded with a singer as the director was felt that no vocals matched with Sonam Kapoor's voice. The director Anand L. Rai attributed the melody and beauty of the particular song to "Mujhe Kuch Kehna Hai" from the 1973 film Bobby. In an interview with Hindustan Times, Rahman stated that he had emphasized the folk-classical genre as the film brings out a fascination for Benaras through the music and most of the songs are character-driven. The composer stated that he had used the sounds of shehnai in almost every song, thereby paying a tribute to Ustad Bismillah Khan. Whilst doing reconnaissance for the film, the film director recorded the live aarti chants for the score, however, the patch recordings were fit into a complete song titled "The Land of Shiva". Six songs were recorded by 23 November 2012. The soundtrack album composition was completed by early March 2013. The audio rights were acquired for a sum of ₹60 million (US$930,000).
