## Background and composition

"Boom Clap" is a "radio-ready" electropop and synth-pop ballad, written by Charli XCX, Fredrik Berger, Patrik Berger and Stefan Gräslund. The song was initially written during writing sessions for XCX's debut studio album, True Romance, then later offered to singer and actress Hilary Duff for her new album. Once Duff's management declined the offer, XCX decided to use the song as her contribution to The Fault in Our Stars motion picture soundtrack. In a later interview, Duff said she had no idea that XCX had offered the song to her people and would have accepted the song if she had known. The song is composed in the key of E major.

## Critical reception

"Boom Clap" received positive reviews from music critics. 4Music said the song was "infectious" and a "feelgood track [which] contrasts softly-sung verses with a big attitude-packed chorus" resulting in a song that was "catchier than the clap." Spin listed "Boom Clap" at number 24 on its list of "The 101 Best Songs of 2014," writing that "Charli XCX's excellent use of onomatopoeia gives this intoxicated Sucker cut her most unforgettable chorus yet." Pitchfork named it the 37th best song of 2014. In January 2015, "Boom Clap" was ranked at number eight on The Village Voice's annual year-end Pazz & Jop critics' poll. In April 2022, Clash listed the song among the 17 best of Charli's songs, with Isabella Miller stating that "it captures the essence of youth culture with timeless stylistic and lyrical content that awakens the 2014 Tumblr teen in us all."
