Some things to know about emerging Britpop darling Charli XCX: The letters stand for “Kiss Charli Kiss” (but also maybe Xrated Cunt Xrated, if you are feeling scandalous); she co-wrote “I Love It,” the Icona Pop smash that is your leading Indie Song of Summer contender; and she has a heap of glitchy, delightful “goth pop” singles to call her own. (Vulture’s partial to “Valentine,” but you’ll want to check out “Stay Away” and “Nuclear Seasons,” too.) If you’re still on the fence, consider the video for “You’re the One,” which features Charli in Robyn mode — warehouse dancing, platforms, aggro tutus. There is also an army of laser-controlled children in leather vests. And glitter. Get on this bandwagon; it's so sparkly and fun.
