“Bad Guy” by Billie Eilish is one of the defining pop songs of 2019 and a breakthrough global hit from her debut studio album, When We All Fall Asleep, Where Do We Go? Released on March 29, 2019 by Darkroom and Interscope Records, the song was written by Billie Eilish and Finneas O’Connell, with Finneas producing the track. It was released as the album’s fifth single and helped establish Eilish as one of the most distinctive pop artists of her generation.

Musically, “Bad Guy” blends electropop, dance-pop, pop-trap, and goth-pop with a minimalist and playful production style. The main musical elements include synth bass, kick drum, 808 bass, amplified finger snaps, a cartoon-like synthesizer hook, and Billie Eilish’s close, whispery vocals. The song is written in G minor and is divided into two sections: the first part moves at around 135 BPM, while the second half slows down to around 120 BPM.

The lyrics play with the idea of power, attitude, and identity. Eilish taunts someone who presents himself as tough, while suggesting that she is actually more fearless and unpredictable than he is. Her half-spoken delivery, sarcastic tone, and famous “duh” moment helped make the track instantly recognizable.

“Bad Guy” became a massive commercial success. It reached No. 1 on the US Billboard Hot 100, ending the record-breaking 19-week run of “Old Town Road” by Lil Nas X featuring Billy Ray Cyrus. It also topped charts in countries including Australia, Canada, New Zealand, Finland, Greece, Iceland, Norway, and Russia, and became the best-performing global single of 2019 according to IFPI figures cited in the article.

One curiosity about “Bad Guy” is its unusual sound design. The song includes a sound recorded from a Sydney pedestrian traffic light, captured by Billie Eilish on her phone in 2017. Another interesting detail is that the song’s strange, playful mood was influenced by unexpected sources, including the theme from Wizards of Waverly Place and music from the video game Plants vs. Zombies.

The music video, directed by Dave Meyers, became famous for its eccentric imagery: Eilish dances wildly, suffers a nosebleed, pours milk and cereal from her mouth, and sits on the back of a man doing push-ups. The video’s camp and surreal style reinforced the song’s darkly humorous identity.

Another notable curiosity is the Justin Bieber remix, released in 2019. Bieber had been one of Eilish’s childhood idols, so the collaboration was personally meaningful for her. The song also won Record of the Year and Song of the Year at the 62nd Annual Grammy Awards, confirming its status as one of the most important pop releases of the late 2010s.

White shirt now red, my bloody nose
Sleepin', you're on your tippy toes
Creepin' around like no one knows
Think you're so criminal
Bruises on both my knees for you
Don't say thank you or please
I do what I want when I'm wanting to
My soul so cynical

So you're a tough guy
Like it really rough guy
Just can't get enough guy
Chest always so puffed guy
I'm that bad type
Make your mama sad type
Make your girlfriend mad type
Might seduce your dad type
I'm the bad guy, duh

I'm the bad guy

I like it when you take control
Even if you know that you don't own me
I'll let you play the role
I'll be your animal
My mommy likes to sing along with me
But she won't sing this song
If she reads all the lyrics
She'll pity the men I know

So you're a tough guy
Like it really rough guy
Just can't get enough guy
Chest always so puffed guy
I'm that bad type
Make your mama sad type
Make your girlfriend mad type
Might seduce your dad type
I'm the bad guy, duh

I'm the bad guy
Duh
I'm only good at bein' bad, bad

I like when you get mad
I guess I'm pretty glad that you're alone
You said she's scared of me?
I mean, I don't see what she sees
But maybe it's 'cause I'm wearing your cologne

I'm the bad guy
I'm the bad guy
Bad guy, bad guy
I'm the bad
