Lorde is "heartbroken" to have finished work on ‘The Hunger Games: Mockingjay – Part 1’ soundtrack.
The ‘Royals’ hitmaker curated the music for the latest installment of the futuristic fantasy adventure series and was thrilled to work alongside artists like Grace Jones, Charlie XCX, Ariana Grande and Haim.
She said: "It was fun getting to approach my favourite musicians and just say something to them for this project.
"I feel like school camp has ended and I’m heartbroken this project is over."
And the 18-year-old singer admits she was very "teenage" in her approach to putting together the roster of artists who appear on the soundtrack because she relied heavily on social media to ask people to work with her.
Asked how she approached the artists, she said: "I DM-d (direct messaged) a lot of people and Instagram DM-d a lot of people.
"It wasn’t very professional, it was very teenage.
"I guess we just kind of cold-called a lot of people and they were like, ‘Who’s this weirdo.’ "
Lorde found the experience very different to putting together an album of her own because there were so many people to consider.
She said: "It’s so different and I don’t think I realised how different that would be.
"You really have to think about everyone else rather than yourself so much because you are involved with so many other artists and different demographics of people who are already into this film.
"I really felt responsibility to do something they would like, so hopefully there’s something in it for everyone."
