'Shake It Off' made everybody dance when it debuted last week- so Paul interviewed Sam Smith, Mary Lambert, Ed Sheeran, Nick Jonas, Charli XCX, Jack Antonoff of The Bleachers and more VMA guests using ONLY lyrics from Taylor Swift's latest song!
As T-Swift would say...the player's gonna play (play, play).
