Bit by bit, we’ve been treated to snippets of information about what to expect from the Lorde-curated Hunger Games: Mockingjay Part 1 soundtrack. So far, that’s included full tracks of Lorde’s “Yellow Flicker Beat” and team up with Chemical Brothers and Miguel, “This Is Not a Game,” as well as a track list that was complete with names including Kanye WestChvrches and Charli XCX, except for one song listed initially as just “Track 5” by unnamed artists.

Now, Lorde has announced that mystery track is a team up between Ariana Grande and Major Lazer for a song called “All My Love.” The singer blasted the news on Twitter Monday.
