Charli XCX 2014
Kaitlin Christy

Charli XCX currently has two Top 10 hits on the Hot 100 chart -- "Fancy," Iggy Azalea's inescapable smash, and her own "Boom Clap," which marks her first Top 10 single as a lead artist. Yet the prolific singer-songwriter has already dropped another pop gem on our unsuspecting heads, as "Break the Rules" previews her eagerly anticipated sophomore album, Sucker, due out Oct. 21 via Neon Gold/Atlantic Records.

The song, which premiered on Buzzfeed on Monday (Aug. 18), stacks its energy upon a defiant chorus in which Charli sneers, "I don't wanna go to school/I just wanna break the rules," and then defuses its anger with a snappy synth melody worth locking your bedroom door and dancing around in your underwear to. "Break The Rules" showcases the well-crafted hooks that bursted throughout the singer's debut album, True Romance, but its arrangement is even more streamlined, as the most sugary bits are lovingly accessible.

"I never want to make the same thing twice," Charli told Billboard in May. "I never want to make another True Romance -- I want to make something different and something special. I remember when I went into the studio with Stargate, and they had this beat that they wanted me to write on, and it had the same tempo as [Icona Pop's] 'I Love It.' They were like, 'This is your thing now!' And I was like, 'No! Oh no!'"

While True Romance featured singles like "You (Ha Ha Ha)" and "You're The One," "Boom Clap" broke through after being featured on the soundtrack to The Fault In Our Stars. The single reached the Top 10 last week, in its 10th week on the chart.
