Billie Eilish has opened up about the writing process behind her song for the Barbie soundtrack, ‘What Was I Made For?’.Released in July, the track was written by Eilish alongside her brother and collaborator Finneas. It appears in Greta Gerwig’s 2023 hit Barbie film, which also features songs from the likes of Lizzo, Dua Lipa, Haim and Tame Impala.During a new interview with Allure, Eilish recalled how ‘What Was I Made For?’ came about at a time when she was creatively uninspired.“It was as if this song was a tiny creature inside of me for years, scratching the inside of me,” she remembered.
