Taylor Swift and Charli XCX are two of music’s biggest pop stars right now, but they’re on very different ends of that spectrum: Taylor’s more “daydream†and Charli’s more “nightmare†(in the best way possible). Join the two and you get Charli’s frenetic, Ramones-inspired cover of “Shake It Off†— sans the “this sick beat†line because, apparently, trademarking a lyric means everyone else is banned from ever singing it again.
