On Monday, Lorde gave us a few hints about her upcoming song for "The Hunger Games: Mockingjay-Part 1."

The 17-year-old singer released the cover art for the song, which is called "Yellow Flicker Beat," notes Variety. The single will be available for purchase on iTunes on Sept. 30.

It was announced in July that Lorde would curate and contribute to the soundtrack. Director Francis Lawrence said he chose Lorde because she was very in tune with the material.

"I sat down with Lorde on the set of 'Mockingjay' this spring and I was immediately struck by how she was so innately understood that we, as both fans and filmmakers, were trying to accomplish with the film," Lawrence said.

He said Lorde understood the themes and characters of the movie, and that it made her the right fit for the soundtrack.

"But her insight and passion for our project make her the perfect creative force to assemble the other songs on our soundtrack," he said. "I can't wait to share what she's done with the fans -- it is truly remarkable."

Lorde was equally as excited and said that though it was a challenge, she was definitely all for taking on the task. She also said that her "cinematic leanings" helped her with completing the soundtrack, and she thought people would be surprised by the result.

Her song "Everybody Wants To Rule The World," was featured on "The Hunger Games: Catching Fire" soundtrack.

Meanwhile, Lorde is still adjusting to some parts of fame. For example at Lollapalooza in Chicago, Lorde was stunned by how many people came out to see her.

"There are more people here than in my whole town, than in my whole high school, and than all the people at the airport in New Zealand," she said. "And that to me is just so crazy, that for some reason the gods declared that this many of you were going to hang out with me."
