The Hunger Games: Mockingjay — Part 1 is the biggest movie in the world right now, so it only makes sense that the music from the film is doing well. However, it's not Lorde's contribution to the film, "Yellow Flicker Beat," that's surprising people on charts everywhere: it's Jennifer Lawrence's rendition of the film's song "The Hanging Tree." Sang by her character Katniss, it happens in a pivotal moment in the movie, making it one of the year's most searched-for songs. Currently sitting on the UK singles chart at no.29, there's no doubt the track will make its way up towards the top in the coming weeks. This is the second time in recent years that an actress is making her debut on music charts, the last time being Anna Kendrick's "Cups," which was the fan favorite from the movie Pitch Perfect. We don't think it will take long for "The Hanging Tree" to land on the Billboard Hot 100 as well.
