Charli XCX is living by her own rules in her new rebel anthem 'Break the Rules,' the first single off of her upcoming sophomore album 'Sucker.'

The British singer has a few major hits under her belt, including Icona Pop's 'I Love It' and and Iggy Azalea's 'Fancy,' both of which she featured on and helped to write. With her catchy 'Boom Clap' also rocketing up the charts, it's safe to say that Charli knows how to write and pick good tunes!

'Break the Rules' is no exception, and makes the perfect lead single for an album titled 'Sucker.' It's a pop-punk anthem that brings to mind images of high school and college students pumping their fists and shredding their homework. A little dramatic, maybe -- but you'll understand when you hear the song, which includes chanting lyrics such as, "Going to the discotheque / Getting high and getting wrecked / I don't wanna go to school / I just wanna break the rules."

“The song is inspired by a lot of the things I was listening to whilst in Sweden at the end of last year,” Charli told BuzzFeed. “I spent about a month making a punk record and covering songs by Swedish punk bands like Snuffed By the Yakuza and stuff. This song was written when I came out of the other side of that punk phase and translated it into something more pop. Obviously, it’s about not giving a f---.”
