5. "Blank Space" (2014)
A double-venti celebration of serial monogamy for Starbucks lovers everywhere, as Tay zooms through the whole cycle – the high, the pain, the players, the game, magic, madness, heaven, sin. Every second of "Blank Space" is perfect, from the pen clicks to the "nasss-taaaay-scarrr" at the end. The high might not be worth the pain, but this song is.
Best line: "Darling, I'm a nightmare dressed like a daydream."
