Billie Eilish's producer-songwriter brother just wants his sister to be happy.
Finneas O'Connell, 22, revealed that he and his family were "insanely concerned" when they first heard the Grammy winner's dark song Everything I Wanted.
"It was a period where I was really worried about my sister, and I felt like an enabler in helping her write a song as bleak as that song was," he told New York Times magazine.
"Like the musical equivalent of giving an alcoholic another beer: 'I'm not going to support this.'"
However, the singer explained the song's inspiration in-depth to the magazine, which featured the song in its annual "25 Songs That Matter Now" list, ranking it at No. 7.
"We had this big argument," Eilish said of her brother.
"Because I admitted something that I was, uh. It wasn't a physical thing I was admitting. I don't know how to put it without actually saying it, and I don't want to actually say it. But it was me admitting to something that was very serious about my depression. A very serious step that I was admitting that I was planning on taking."
Ultimately, O'Connell got what he wanted, in a way, by producing a song that was authentically Billie but added a glimmer of hope.
"Thought I could fly/So I stepped off the Golden/Nobody cried/Nobody even noticed," Eilish sings in the verse. But in the chorus, O'Connell harmonises with his sister: "You say, 'As long as I'm here, no one can hurt you.'"
"Finneas and I both had the idea to make the song about each other, instead of just me and how I was feeling," Eilish said. "We had a complete block, and the way we got through it was to make it about us as siblings and what we mean to each other."
Eilish also told the magazine that she's struggled with depression since her adolescence, and death is a common theme in her music. In the morose Bury a Friend, she croons, "I wanna end me," and the song Bellyache references thoughts of murdering her own friends.
