Billie Eilish broke all kinds of records with her debut studio album, 2019's "When We All Fall Asleep, Where Do We Go?"
The 19-year-old was due to embark on a world tour in 2020. Instead, she hunkered down with her family in Los Angeles and made significant headway on her sophomore effort.
"As much as I wished that I had been able to have the year I was planning on having... we would never have made this album," she told Apple Music in November. "I can't wait to have the world hear. I'm very excited and hopeful about the future."
Eilish released two singles in 2020, "My Future" and "Therefore I Am," in addition to her James Bond theme song, "No Time to Die."
During her annual "time capsule" interview with Vanity Fair, Eilish said she has 16 additional songs in the works.
"We've been working," she said, referring to herself and her brother, Finneas O'Connell. "And I love them all."
"I think Finneas and I have just seriously really gotten in the groove. We do it so fast," she continued. "There was a period of time, a month ago or something, we were just texting the label like, 'Song done, another song done, another song done.'"
In December, Eilish also said a "new era" will begin after her documentary is released in February: "I have announcements to make, I got some s--- to put out."
