For the male vocals of the song, Mallik wanted a voice that does not sing many peppy numbers. The song is sung by Arijit Singh and Aditi Singh Sharma.

According to him the song is something every person in this world can relate to and it is 'a party song with a simple melody, Electronic Dance Music beats and non-crass lyrics'. With the first verse of the song written by Kumaar, which was 'cracked' in fifteen minutes, Mallik realised that they 'hit upon something really special'. Singh wanted the track to be about being young and carefree, similar to those which can be played in clubs too. The director of the film Vikramjit Singh gave Mallik an insight into Ranbir Kapoor's character, a carefree person who believes one should forget everything and live freely. After composition he wasn't aware that the song was composed for the film Roy until Bhushan showed him the poster of the film for which he has composed the song. Bhushan Kumar, associated in producing the film, heard the version along with other tracks he had composed and wanted to hear the final version of the song, for which Kumaar wrote the lyrics. Mallik finalised a rough version of 'Sooraj Dooba Hai' with a few lines written, which was originally composed by him three years ago and was rejected by many of the film producers. Initially, Bhushan Kumar told Malllik, that he was looking for a youthful party song for the film, and offered the chance to five other music composers, in-order to select the best track. The song is composed by Amaal Mallik who made his debut in Bollywood as a music director with the 2014 released film Jai Ho. Commercially, the song fared well, topping the iTunes chart of Indian and Cambodian, along with 91.9 Friends FM weekly chart. The single of the song was digitally released on 22 December 2014. The music video of the song was officially released on 19 December 2014 and was exclusively released on. The video track shows Fernandez romancing both Kapoor and Rampal. The song is all about living the present moment with someone special. Producer of the film, Bhushan Kumar heard the rough version of the song composed and written by Mallik and wanted to hear the final version of the song, for which Kumaar wrote the lyrics. The music video of the peppy, dance track features actors Jacqueline Fernandez, Ranbir Kapoor and Arjun Rampal.
