Billie Eilish and her brother, Finneas O’Connell, had a ‘huge argument’ while recording her new album, Hit Me Hard And Soft.

The 22-year-old hitmaker and her frequent collaborator, 26, disagreed on the album’s ‘context and subject matter’.

During a recent episode of The Zane Lowe Interview Series, the producer confronted the singer over her treatment of the album’s topics, revealing their disagreement.

‘We’d been writing these scraps of stuff, and I felt…I’d been proven wrong time and again, but this was the jag I was on that night. I said, “Subject-wise, I’m not being led into what you’re really feeling. And I believe that there are actual guards up.”

O’Connell also mentioned that Eilish was frequently ambiguous about the meaning of each of her songs, and he told her to’say how you feel’ when explaining the background behind her lyrics.

However, the suggestion led to an argument, and the singer recalled that her brother’s reaction to her reticence was particularly unnerving.

The hitmaker then opened up about her love-hate relationship with the process of recording music.

‘I used to be like, “[I] hate making music, [I] don’t want to make it, [I] don’t like making it”…I love performing it. I love when it’s good, but I really have always struggled with the process,’ she said.

Eilish added that she was ‘finally enjoying the process’ when she began arguing with her brother.

‘It was very interesting because I saw myself in that. I was like, “I have felt that way and you have always been the thing that keeps the ship moving, and now you feel that way,”‘ she recalled.

O’Connell concluded by speaking about how he found that being able to connect emotionally with his collaborators led to stronger results in the studio.

‘I think that…my whole strength as a collaborator with any artist, and it’s always been innate with Billie because we’ve shared so much, is I do have to understand that person to be able to feel like I’m providing something,’ he said.

Hit Me Hard And Soft was preceded by Eilish’s first two records, When We All Fall Asleep, Where Do We Go? and Happier Than Ever, which were released in 2019 and 2021, respectively.
