"Yellow Flicker Beat" isn't just the new Lorde single and video -- it's also the lead track from part one of the final Hunger Games film, Mockingjay. Lorde curated the film's soundtrack, and she enlisted artists like Chvrches, Charli XCX, Haim, Q-Tip, Pusha T, and Kanye West.
Kanye didn't hit the studio to rap, though. Instead, he's done an atmospheric flip of "Yellow Flicker Beat." Yeezy's touch is sparse -- he didn't throw in a big soul sample or a "that shit cray" one-liner. He mostly added some ominous synths (touches of "Clique"), some light keys (slightly "Runaway"-ish), and a bass thump and echo effect that would make James Blake and Kanye's buddy Bon Iver smile. The further the song progresses, the more Kanye turns up his additions. Toward the end, there's some eerie, Yeezus-y feedback.
