The song was composed by Amaal Mallik who made his debut in Bollywood as a music director with the 2014 film Jai Ho.

[5] Mallik finalized a rough version of "Sooraj Dooba Hain" with a few lines written, which he had originally composed three years ago and had been rejected by many film producers.

[7] 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.

At the studio Mallik briefed her to do improvisations as per her wish; "After my solo parts were done, we worked on ideas for suitable harmonies for Arijit's lines, for the chorus as well".

[21] When in the same frame with Kapoor, she is seen sporting a faux bob hair style, but she is dressed very casually with long tresses, accessories including bands and bracelets, and a tattoo on her neck and wrist when in the company of Rampal.

[24] Apart from the lyrics, the video also shows product placement for the company in the background, when Fernandez and Rampal dance to the beats of the song in an uptown club.

Bollywood Hungama's Rajiv Vijayakar calling it a "nice celebratory song" appraised the "interesting and meaningful lyrics" by Kumaar and the vocals by Singh, though felt that; "it needed a lively and full-throated singer rather than Aditi Singh Sharma crooning with a put-on Westernized accent, and that too very superficially from her mouth".

[35] According to Joginder Tuteja from Rediff.com, Mallik deserves full marks for the track; "It's a beautiful tune with a good mix of rhythm and melody [...] and has a club sound but still makes for pleasant listening".

[36] Sankhayan Ghosh of The Indian Express was impressed with the arrangement of the tune, though he felt the song "shows a serious lack of imagination".

[37] Rucha Sharma from Daily News and Analysis wrote: "For a change, it's good to hear Arijit Singh singing happy tunes.

Redkar opining that "it is surely going to be one of the party songs of the year", complimented that Mallik composition has a lot of energy to "drive" to the dance floor.
