Lorde's new single Green Light has taken the music world by storm since its release earlier today, with one fellow star calling it a "magnificent bop for the ages".
The Kiwi superstar unveiled her new single after much secrecy and rumour, but fans and critics have been quick to declare the track a hit.
Billboard described Green Light as a song which "barges into your heart on its first play".
"Lorde makes a good case that her songwriting, above all else, is her strongest asset," the weekly music magazine said.
"Green Light is towering because of the tiny details surrounding its euphoric hook, moments and memories carefully stacked upon each other."
