Charli XCX Is More Gloom Than Boom On 'Hunger Games' Track

'Kingdom' is seriously pretty — in a creepy kind of way.

Charli XCX may be going punk-rock for her upcoming record, Sucker, but on her "Hunger Games: Mockingjay -- Part 1" track, "Kingdom," she's as delicate and intricate as some kind of ancient tapestry.

The song -- which is basically the anthesis of tracks like "Boom Clap" and "London Queen" -- shows that Charli can get gentle, her voice draping over soft piano until the drop, which brings in violins and an almost anachronistic-feeling drum track.

Charli told Pitchfork that she worked with Duran Duran’s Simon Le Bon and Vampire Weekend’s Rostam Batmanglij on the song, the latter of whom she got wasted with at a Miley Cyrus show before penning the tune. "We went back to his house and I sat on top of [Batmanglij's] piano, and we wrote 'Kingdom,'" Charli said. "We sung it into his phone. I remember thinking in the morning, 'Ugh, this is going to be the worst thing ever,' but it was really good."

Lorde, who curated the entire soundtrack, was apparently pleased with the results as well.

As the release date on the film -- November 21 -- creeps ever closer, more and more music from the movie's track list have hit the Web, including Lorde's "Yellow Flicker Beat" and Kanye's remix of that track, as well as the 17-year-old singer's cover of Bright Eye's "Ladder Song."
