Billie Eilish has announced that she’s been using her time in the quarantine to work on a new album. The singer made this revelation while speaking to Zane Lowe of Beats 1.

“We’ve been in the ‘stu,’ which just means Finneas’ basement, basically. We actually, we wrote a whole song in its entirety—an entire song, which is kind of rare for us. I really love it. It was like exactly what I needed to say when we wrote it.”

Billie also went on to affirm how positive she felt, despite the prevailing circumstances.

“Honestly, I feel great,” she said. “The song I was talking about earlier that we wrote a couple weeks ago that felt so right was … I wish I could sing it for you, but I can’t. It was just about, there was this part in it—I needed to say this—which was I know I’m supposed to feel unhappy right now because of this break and because I’m not seeing anybody … I feel like there’s this kind of thing that I feel like is floating around of like you’re supposed to be missing people. You’re supposed to be missing this person and be missing people in general. I kind of have this feeling of like, I miss my really close friends, I miss people, of course I do, but I also at the same time am liking the space.”
