Junior thinks this is Katy Perry, but all three of them know all the words.

And that’s Charli XCX in a nutshell. Thank you.

(Other than that, simple but hugely effective pop song – with an onomatopoeic but also self-fulfilling title/chorus that Junior appreciates (“It’s like, ‘BOOM! CLAP!'”) – sulked out by someone who doesn’t appear to play the game, hence relative lack of recognition, but who might end up at its top. Kind of startling that a blogstar’s breaking through. Come back in 2015 for a trio of No.1 singles from Jai Paul.)
