You may know British pop singer Charli XCX best for her work on Icona Pop’s ubiquitous “I Love It” single, or possibly for her buzzy and critically acclaimed debut album, True Romance. But after you watch the above video, you will forever know Charli XCX first and foremost as one very crucial thing: a sensational Backstreet Boys cover artist. Not only does she completely commit to “I Want It That Way,” one of the most freakishly indelible pop singles of the last twenty years, but she manages to apply enough of her own personality to make it her own. And that, my friends, is the mark of a truly exemplary cover.
