2015년, 열 세살이 된 아일리시는 오빠인 [[피니어스 오코넬]]과 함께 곡들을 작업했다. 오빠는 이미 수년 전부터 자신의 밴드를 결성하여 곡을 쓰고 있었다. 처음으로 함께 녹음했던 곡들은 <She's Broken>과 <Fingers Crossed>였는데 이에 대해 아일리시는 "처음 작업한 곡들은 오빠와 같이 쓴 것은 아니었다. 오빠가 <She's Broken>을 썼고 내가 <Fingers Crossed>를 쓰고 녹음해서 재미삼아 [[사운드클라우드]]에 올렸었다"고 했다.<ref>{{웹 인용|url=https://variety.com/2019/music/news/billie-eilish-finneas-oconnell-songwriting-1203421768/|title=Billie Eilish and Brother/Co-Writer Finneas Get Deep About Songwriting|work=Variety|date=December 4, 2019|access-date=December 16, 2020|archive-date=June 8, 2020|archive-url=https://web.archive.org/web/20200608003654/https://variety.com/2019/music/news/billie-eilish-finneas-oconnell-songwriting-1203421768/|url-status=live}}<br />{{웹 인용|url=https://medium.com/jellyjrnl/who-is-billie-eilish-15683d980a58|title=WHO IS: Billie Eilish.
