Billie Eilish's new album might be called Happier Than Ever, but she insists the collection isn't as upbeat as it appears.

The Your Power singer channeled a lot of "anger" and "frustration" into the songs on her hotly-anticipated follow-up to her acclaimed 2019 debut record When We All Fall Asleep, Where Do We Go?.

Speaking to the latest issue of British Vogue magazine, of which she is the cover star, Billie says, "It was very satisfying to scream. Because I was very angry. There's so much anger in those songs – anger and disappointment and frustration."

The Therefore I Am hitmaker also touched on how her songwriting has matured as she discussed the positives to come out of the global pandemic.

"I've grown so much and gotten so much better in my voice, it's crazy to think about. I think change is one of the best gifts in the world," she added.

Billie releases Happier Than Ever on 30 July, which she has hailed as her "favorite thing" she's "ever created".
