On Instagram, Eilish explained how the song came to be, writing, “‘What Was I Made For?’ our barbie song (& video) is out now. :’) in january greta showed me and finneas a handful of some unfinished scenes from the film; we had nooooo idea what to expect at ALLL… we were so deeeeeply moved.. that the next day we were writing and COULDNT shut up about it lolll andddddddddd ended up writing almost the entire song that night. to be real with you this all seemed to happen in a time when i really needed it. i’m so so thankful for that.
