Musically an electronica and pop track with a hip hop-influenced instrumentation, the song was heavily inspired by someone who kept on copying Eilish and what she did. Commercially, "Copycat" peaked at number 12 on the Billboard Bubbling Under Hot 100 chart and number 100 on the Canadian Hot 100. It has also received several certifications, notably a double platinum award from the Mexican Association of Producers of Phonograms and Videograms, A.C. (AMPROFON). The song was performed live during Eilish's 2019 When We All Fall Asleep Tour and her Where Do We Go? World Tour in 2020. A Sofi Tukker remix was released on January 12, 2018. Background and release "Copycat" was released on July 14, 2017, as the fourth single on Eilish's debut EP Don't Smile at Me. "Copycat" was written by the singer and Finneas O'Connell, her brother and the track's sole producer. Mastering and mixing was handled by the studio personnel, John Greenham, and Rob Kinelski, respectively. In an interview with Genius, Eilish mentioned that she wrote the song with her brother about a girl who copies everything that she does. "I write with my brother mostly. That song, we were just in his room, and I was like, 'Yo! There's this fucking girl and she keeps doing everything that I do. And I want to write about it.' Because it was in my mind." A remix by Sofi Tukker was released on January 12, 2018. Dan Regan of Billboard praised the remix, saying its tone "beefs up [Copycat] with a club-ready rhythm", and has a "flush of colors in its disco cheeks as new layers of synthetic brightness come in waves."
