If you were captivated and haunted by Beyoncé's jaw-dropping performance at the Grammys, just wait. On Tuesday, the isolated vocals from the microphone began making their rounds on Twitter, and they're so flawless, you'll almost doubt they're real. At the same time, these riffs on "Sandcastles" and "Love Drought" prove exactly why Bey is an icon in the first place . . . even if the Grammys refuse to recognize that fact. We'll just have to know in our heart of hearts, like Adele, that Bey really deserved to win, and this video is just one of many reasons.
