Music director and singer Mikey McCleary composed the soundtrack for Margarita with a Straw, with Joi Barua serving as the guest composer for both versions of the song "Dusokute". The lyrics for the album were written primarily by Prasoon Joshi, except for the tracks "I Need a Man" and "Don't Go Running Off Anytime Soon", the latter featuring English lyrics written by McCleary. Artists such as Sharmistha Chatterjee, Sonu Kakkar, Anushka Manchanda, Rachel Varghese, Vivienne Pocha, and Rajnigandha Shekhawat provided vocals for the album on various tracks. The first track to be released, the soft rock number "Dusokute", was originally composed by Barua in Assamese and was rewritten in Hindi by Joshi. In April 2015, the complete soundtrack was released under the Zee Music Company label.
Critics such as Kasmin Fernandes and Joginder Tuteja gave positive reviews of the soundtrack's unconventional style. The former appreciated Barua's "energetic vocals" in "Dusokute" and the "desi yet classy" number "Foreign Balamwa" in her 3-out-of-5-star review for The Times of India. She described the lyrics by Joshi as "cheerful", but was less impressed by McCleary's "passable" writing. Tuteja, writing for Bollywood Hungama, noted the album's lack of a commercial appeal and wrote that at best it "fit[s] in well into the stage and setting that the film stands for". He praised McCleary's command of the English compositions and his "boyish charm" as a vocalist. Tuteja was particularly impressed by Pocha's "thumping vocals" in "I Need a Man" and the serene effect of the final two tracks of the album. He also found the choice of such artists as Manchanda and Kakkar odd for what he described as an album heavily influenced by Western music. Bryan Durham of the Daily News and Analysis considered the duo's respective tracks "unusual" and "candid". He singled out the instrumental number, "Laila's Theme", as "the beating heart of the film".
