Billie Eilish Says Her 2019 Hit 'Bad Guy' Is the 'Stupidest Song in the World'

"It’s literally, like, 'Duh.' Like, what does that mean?" Eilish said on 'Jimmy Kimmel Live!'

Billie Eilish thinks "Bad Guy" is the "stupidest song in the world," but it "works."

The pop star, 21, opened up about her 2019 hit on Jimmy Kimmel Live! during Tuesday night's episode when the show's host asked if there was a song that made her "uncomfortable" now.

“Objectively, ‘Bad Guy’ is like the stupidest song in the world, but it’s really good,” she told Kimmel. “It’s just like you have to understand, you have to have humor in it. Like, [on] that song I’m trolling. That song is supposed to be goofy, but it’s just funny because it’s dumb. It’s literally, like, ‘Duh.’ Like, what does that mean?”

The "Everything I Wanted" performer also discussed her thoughts on artists who are “very hateful towards their own music,” explaining that it's “really frustrating because why are you doing this then?”

“I feel like we both are, like, fans of what we make,” she said of her work with Finneas. “I love my own music, and it definitely just changes and morphs with me and becomes whatever. I still cringe but I appreciate it, though.”

Elsewhere in the interview with Jimmy Kimmel, Eilish discussed her hit single from the Barbie soundtrack "What Was I Made For" and how she and her brother, 26, "kind of thrive" when they they are being "frank."

"When we are being given a prompt, that is when we make my kind of favorite thing," she said. "I feel like it's pretty hard for me to write my exact kind of feeling. I feel like that kind of goes for life in general: it’s hard to know how you feel in the moment. It’s much easier to, like, look back and go, ‘Damn, that’s how I was feeling,' and I feel like I do that a lot."

“With music, I find it really hard to sit and write how I’m feeling, just from my own perspective and my own experience. I just have this feeling of ‘Ah, boring. Nobody cares. Everyone’s heard that before,'" she explains, before adding, that this song "was an assignment but it turned out to be how I felt."

In a recent cover story for Allure, Eilish revealed that "What Was I Made For" came together at a time that she and Finneas "couldn’t have been less inspired and less creative, but she said it "wrote itself."

"I have the whole video of us writing the song, and the first thing we wrote were those lines in the first 10 minutes," Eilish told the outlet. "We wrote most of the song without thinking about ourselves and our own lives, but thinking about this character we were inspired by."

"A couple of days went by, and I realized it was about me. It’s everything I feel. And it’s not just me —everyone feels like that, eventually.”
