Giant in My Heart

"Giant in My Heart" is a song by Canadian recording artist Kiesza from her debut EP Hideaway (2014) and her debut studio album, Sound of a Woman (2014). It was released by record label Lokal Legend as the second single from both the EP and the album on August 8, 2014. The song was co-written by Kiesza and Rami Samir Afuni, and produced by the latter. "Giant in My Heart" is an electropop and house track sung in an emotive falsetto tone and features a combination of scat-singing, a pounding 808 and softer synth-led sections. Lyrically, the song focuses on subjects of love lost and the aftermath of a breakup.

"Giant in My Heart" garnered positive reviews from contemporary music critics, who commended the song for its sonic similarities with Kiesza's debut single "Hideaway" and the singer's strong vocal performance. It was a commercial success, debuting at number four on the UK Singles Chart, number one on the UK Dance Chart and selling 33,414 copies in its first week. "Giant in My Heart" marked Kiesza's second consecutive top five single in the United Kingdom and has also had success in Germany and Belgium where it peaked at numbers 11 and 12 respectively. The song was accompanied by a short film music video directed by producer Afuni in New York City. The clip premiered on July 1, 2014 and was acclaimed by several critics. It features a frustrated male office worker living a double life as a crossdresser. Kiesza has performed "Giant in My Heart" on American television show Jimmy Kimmel Live!, and the song has been covered by English singer Florrie.
