What Was I Made For is self-directed and written by Billie Eilish and help from her brother Finnas. Billie contributed this song to be a part of the new Barbie movie soundtrack. It touches on mental health and has a deeper meaning for little girls and women, hitting many soft spots.

Billie took to Instagram, sharing that she and her producer, who is also her beloved brother, Finneas, “were so deeply moved” after watching scenes from Barbie with director Greta Gerwig. “The next day we were writing and couldn’t shut up about it lol and ended up writing almost the entire song that night,” she wrote. “To be real with you, this all seemed to happen in a time when I really needed it. I am so thankful for that.”
