Charli XCX wanders around city in "Boom Clap"

Charli XCX, who recently scored her first U.S. No.1 thanks to Iggy Azalea's "Fancy," has premiered the Amsterdam-set music video via MTV.com for her solo new song "Boom Clap," which is the British pop singer's contribution to the soundtrack of "The Fault in Our Stars." It's an appropriate choice for the unorthodox love story between Hazel Grace (Shailene Woodley) and Augustus Waters (Ansel Elgort). The romantic comedy-drama film adaptation of John Green's best-selling novel follows the lives of two cancer patients as they fall in love, suffer, and celebrate together.

It's about time for Charli to have a huge hit under her own name. The mastermind behind Icona Pop's "I Love It" is currently atop the Billboard Hot 100 as the scene-stealer on Iggy Azalea's The New Classic single "Fancy," but this "SuperLove"-worthy electro-pop burst sees her back on her own. Instead of an emotional love song, this upbeat, '80s-sounding pop hit is more of a toe-tapping love anthem than a tear-filled ballad. "The scene that ['Boom Clap'] is in is an uplifting moment in the film, Charli explained to Billboard magazine. "And while the song itself is very euphoric and enthusiastic about romance… it's about wanting to fall in love, but there's this hint of sadness in that, which I like."

The 21-year-old singer-songwriter shot the video in Amsterdam, where "The Fault in Our Stars" was partially filmed in too. Interspersed with dramatic footage, cartoonish scenes and snippets from the movie, the "Boom Clap" clip goes between colorfully doodled-around shots and features Charli enjoying herself and traipsing around the city while wondrous graphics frame her face, as the Brit croons while riding on a boat, gets lost in a sea of bikes, walks the streets, and poses on various canal bridges. 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."

The singer-producer's video is one of these soundtrack videos that haphazardly alternates movie footage with footage of its star. But the video still has a ton of Charli dancing around Amsterdam and looking mad charismatic. If "boom clap" is "the sound of my heart," as the True Romance-r belts out here, she shouldn't be alone in that particular cardiac condition. By the way, although "Boom Clap" hasn't been sent to radios, not it's charting high on iTunes presently, it will presumably appear on the U.K. singer-songwriter's sophomore LP, due out later this year.
