The world premiere of Hunger Games: Mockingjay - Part 1 is just around the corner which means promotions are in full gear, including the release of the carefully curated soundtrack. Very much involved in the process, "Royals" singer Lorde released a song called "Yellow Flicker Beat" back in September. It was a solid track packed with lots of synths and a bouncy slow-beat, typical to what we hear from the young singer. Now, with just over a week to go, we're treated to another version of the song reworked by Kanye West himself. Renamed simply as "Flicker", it features a heavy bass and a more gritty, emotional feel, fitting nicely with the theme of the movie and the state of mind Katniss is in. The song ends with the weird but classic echo-y Yeezy chant. Take a listen below. Hunger Games: Mockingjay - Part 1 comes out November 21.
