The 'Mockingjay - Part 1' track list has yet to be revealed

What a difference a year makes.

On this week in 2013, Lorde leapt to No. 1 on the Hot 100 chart with her debut single “Royals,” and the New Zealand teenager has never looked back. Tapped as the curator of the soundtrack to The Hunger Games: Mockingjay - Part 1, Lorde has shared the lead single from the upcoming set, her own song “Yellow Flicker Beat” — listen below.

With lyrics that reference the rise of Hunger Games heroine Katniss Everdeen (“They used to shout my name, now they whisper it”) and a wiry drop in the hook that recalls the explosion at the heart of “Team,” “Yellow Flicker Beat” finds Lorde honing her art-pop sensibilities in the context of a blockbuster franchise. “It’s my first offering from what i hope will be a soundtrack you love,” Lorde wrote of “Yellow Flicker Beat” in a Tumblr post on Monday (Sept. 29). “It’s my attempt at getting inside her head, katniss’. i hope you like it.”
