Poll: Who Gave the Best Performance?

Following a spirited introduction from Nicki Minaj, Lorde took the stage dressed in a striking all-black ensemble, complete with a wide-brimmed Zorro-style hat. Close-ups showed the singer squeezing the emotion out of every word, as she performed the electro-goth song.

The performance marked the first ever televised rendition of the song, which appears on Lorde's 2013 debut album "Pure Heroine."

The 17-year old New Zealand native has been riding high since "Royals" became a surprise hit last year. It eventually topped the Hot 100 and earned the Grammy for Song of the Year. Subsequent singles "Team" and "Tennis Court" have peaked at 6 ant 71, respectively.
