In high school, she studied jazz piano, and taught herself to play cello. After graduating, she abandoned her plans of becoming a nurse, to focus on music production. Influenced by Australian record producer Flume,[1] Anderfjärd gained first production jobs throughout 2018 and 2019, working on "4U" (2018) by Joakim Molitor featuring Cher Lloyd, debut single of Malou Prytz "I Do Me" (2019), and a remix of Tove Lo's "Glad He's Gone" (2019).[2] In 2020, she joined Max Martin-owned MxM Publishing.[1] She produced two singles from the 2020 reissue of Tove Lo's 2019 album Sunshine Kitty "I'm Coming" and "Sadder Badder Cooler", as well as "What Makes a Woman" (2020) from Katy Perry's sixth studio album Smile (2020).[3] In the following months, she remixed two Taylor Swift songs "Willow" (2020) and "Love Story (Taylor's Version)" (2021), which resulted in speculation about the producer, due to lack of her presence in social media.[1][4] Both remixes amassed 11 million streams on Spotify, as reported by Billboard on 15 April 2021.[1] During 2021, Anderfjärd worked on Molly Sandén's "Kärlek Slutar Alltid Med Bråk",[2]Anne-Marie's "Beautiful",[5] and Swift's "Girl at Home (Taylor's Version)" and "Message in a Bottle".[6] Two years later, she was one of the producers of Alma's Time Machine and Maisie Peters' The Good Witch (both 2023).[7][8]
