The song was originally written by Charli XCX, whom Icona Pop met several times in London. Swedish producer Patrik Berger sent Charli two beats, and she quickly wrote songs for each of them, one of which became "I Love It" and the other of which became her following single "
You're the One". However, she later stated that she knew she would not end up releasing it herself because she could not reconcile it with her sound. While recording "Good for You" with Icona Pop, Berger presented them with Charli's work on "I Love It". Band member Aino Jawo said she felt a connection to the song because it mirrored her own experiences, and the line "You're from the 70s but I'm a 90s
bitch" reminded her of an older man she had known. Member Caroline Hjelt described Charli XCX's original demo as "more cute, in a way…really cool and cocky". Icona Pop approached Swedish producer
Style of Eye to make a rougher version of the track, telling him, "We want the
punkiness. We want the 'fuck it' feeling." ==Composition==
