Along with footage from "The Fault In Our Stars," the "Boom Clap" clip features Charli XCX traipsing around the city while wondrous graphics frame her face. The ending of the video -- the pop singer strolling off down the sidewalk -- is presumably more upbeat than the ending of "The Fault In Our Stars."
Pop Shop Podcast: Is 'Fancy' The Song of the Summer?
Before "Fancy" took over the Hot 100 this year, Charli XCX scored a Top 10 hit last year as a featured artist on Icona Pop's "I Love It" -- although the experience has been "massively different" for her this time around, she told Billboard last month. "With 'I Love It,' there was never a plan for me to go and write for Icona Pop -- they were just there, and it happened, and no one really knew what was going on. … "With Iggy, it's been the flip side of that -- I've been doing TV [performances] in America, which is so crazy for me. I never thought that the first time I was on U.S. television, I'd be doing a dance routine, but I just went with it, and I actually really loved it. From the start, Iggy has been like, 'This is your song as well as my song,' which I think is very nice of her, and it made me very excited about the song. I feel valued."
Charli XCX's fantastic debut album, "True Romance," was released last spring. "Boom Clap" and recent single "SuperLove" will presumably appear on the singer's sophomore LP, due out later this year.
