In January 2013, the song 'Aila Aila' was recorded. Karky called it as the 'most challenging song' he had ever worked on. As some part of the film's story is about modeling, his team created a compilation of six-seven commercials that play to this song. According to Karky, 'The lyrics of Aila Aila was the most difficult to pen as each line will have two different meanings, one is what you hear and one is what you are going to watch on the screen'. The five and a half minute track blends genres like pop, bhangra, opéra comique elements and electronic beats. Shankar stated that he wanted unusual music for I with extensive experimentation. He called the experimentation most evident in this track especially the operatic part. The song slightly touches underlying feeling of romance. Portions of the track 'Ennodu Nee Irundhaal' sung only by Sunitha Sarathy were recorded on 14 February 2013. Rahman was supposed to have sung 'Ennodu Nee Irundhaal' but chose Sid Sriram because the latter sang it well and Rahman felt that Sriram didn't earn the deserving recognition through track 'Adiye' from Kadal, thus gave a second opportunity.

Lyricist Madhan Karky's third song in the film was recorded by mid – September 2013.

In May 2014, Rahman through his bulletin board system of Reddit stated that the film songs have more youth-oriented voices. The track 'Mersalaayiten' was recorded by Anirudh Ravichander and Neeti Mohan in the span of July – August 2014.
