Vanakkam Chennai (soundtrack)

Vanakkam Chennai is the soundtrack album to the 2013 film of the same name directed by Kiruthiga Udhayanidhi and starred Shiva and Priya Anand. The film's musical score is composed by Anirudh Ravichander in his third Tamil film after 3 (2012) and Ethir Neechal, and featured seven songs written by Na. Muthukumar, Madhan Karky, Vignesh Shivan, Hiphop Tamizha and Arjun that featured prominent singers. The soundtrack was released on Sony Music India on 27 July 2013.

Background and production
In September 2012, Anirudh signed to score music for the film which he described as a "fun" and "youthful album" appealing to the urban audiences. When he first approached Kiruthiga, she claimed that his soundtrack for 3 has been one of her favorites and Anirudh has been impressed with her narration. Anirudh described that composing the tunes for the film were "breezy" as he did not have to struggle and Kiruthiga selected him the best tunes for the album.

In May 2013, he recorded a "party" number with Hiphop Tamizha Adhi, which was later deciphered to be "Chennai City Gangsta" with rapper Hard Kaur (in her Tamil playback debut) also singing. On the end of the month, a 40-second teaser of the song "Oh Penne" featured English lyrics written and performed by London-based singer Arjun Coomaraswamy was released. The full song was performed by Vishal Dadlani, in his Tamil debut, recorded the song in June 2013. Coomaraswamy would perform the English version of that song as a part of the album, with singer-producer Charles Bosco.

In late-June, Assamese musician Papon also crooned a song titled "Hey" with Maria Roe Vincent. Pragathi Guruprasad who was a runner-up of Airtel Super Singer Junior 3 performed "Osaka Osaka" with Anirudh, while Andrea Jeremiah and Suchitra also provided vocals for "Engadi Porandha" and "Ailasa Ailasa". The soundtrack was recorded and mixed at the Panchathan Record Inn and AM Studios in Chennai and at the Abbey Road Studios in London.
