“Black Widow” is a song by Australian rapper Iggy Azalea, from her debut studio album, The New Classic (2014). The song’s hook is sung by British recording artist Rita Ora, and its lyrics chronicle subjects of revenge and feminism in a failed romantic relationship. “Black Widow” was written by Azalea, Katy Perry, Sarah Hudson, Benny Blanco, and duo Stargate; the latter also produced the song. On 8 July 2014, the song impacted on mainstream radio stations in the US as the fifth single from The New Classic and the accompanying music video for the song was released on August 13, 2014. The song has currently peaked at number 15 on the US Billboard Hot 100, becoming her third top 15 hit, following “Fancy” and “Problem”.
Initially a track recorded by Perry for her fourth studio album, Prism (2013), the song was excluded from its tracklisting, however Perry handed the demo to Azalea for her to complete. “Black Widow” is influenced by snap and trap genres, containing an ominous steel drum rhythm, heavy bass and a sparse beat. Its composition has been the subject of music critics’ comparisons to Perry’s “Dark Horse”. Other journalists, praised its beat and Azalea and Ora’s vocals. “Black Widow” charted due to strong digital sales during the debut week of The New Classic. Accordingly, before becoming a single it achieved peaks of number 91 in the United Kingdom and number 86 in Australia, and appeared on several component charts. Azalea has performed the song live as part of the set list for her first headlining tour, The New Classic Tour (2014).
