Billie Eilish wonders "What Was I Made For?" in Barbie soundtrack music video

In the video, Eilish—dolled up in ’50s fashion—sits at a desk arranging a myriad of Barbie outfits, struggling as the ground shakes and rain begins to pour. If you pay close attention, the little doll outfits are replicas of some of Eilish’s own iconic looks from the past. And while “What Was I Made For?” can be quite literally applied to the Barbie journey (“Looked so alive, turns out, I’m not real/Just something you paid for”), it also mirrors Eilish’s own feelings as a pop star, a profession that can also turn a person into a product.

Eilish explains her personal connection to the song in a new Apple Music interview with Zane Lowe. She and her brother and collaborator FINNEAS were experiencing writer’s block before seeing the film; she says writing for movies and television provides guidelines that help foster creativity. In writing the lyrics, the singer says she was thinking “purely” about Barbie’s journey and not her own. Yet she realized in retrospect she had almost accidentally captured her own feelings within it. “I find it really hard to write about my exact feelings in my life, and so ‘What Was I Made For’ would never have ever been written, even though it is—every single lyric is exactly how I feel. Exactly how I feel,” she emphasized. Check out the full interview below.
