Ruminating is a 2025 electropop track by British singer Lily Allen, featured on her fifth studio album West End Girl.The song centers on obsessive, anxious rumination—the mental loop of replaying painful thoughts at 4 a.m., unable to sleep. It vividly portrays the narrator’s distress over suspected infidelity, with raw, intimate lyrics about being stuck in “fight or flight” and unable to shake distressing mental images.
It uses a drum-and-bass driven, club-influenced beat that contrasts with the vulnerable, auto-tuned vocals, mirroring the chaos of an overactive, spiraling mind.
I'm giving up on getting sleep tonight
It's 4 a.m. and I'm in fight or flight
Ruminating, ruminating, ruminating, ruminating (ruminating, ruminating)
And I can't shake the image of her naked
On top of you and I'm dissociated
Ruminating, ruminating, ruminating, ruminating (ruminating, ruminating)
And I'm not hateful but you make me hate her
She gets to sleep next to my medicator
You're mine, mine, mine, mine, you're mine, mine, mine, mine
You're mine, mine, mine, mine, you're mine, mine, mine
And now I'm ruminating, ruminating, now I'm in my head
Ruminating, ruminating all the things you said
Why can't you wait for me to come home?
This conversation's too big for a phone call
Ruminating, ruminating, I've been up all night
Did you kiss her on the lips and look into her eyes?
Did you have fun? Now that it's done
Baby, won't you tell me that I'm still your number one?
'Cause you're my number one
I told you all of this has been too brutal
You told me that you felt the same, it's mutual
And then you came out with this line, so crucial
Yeah, "If it has to happen, baby, do you want to know?"
"If it has to happen, baby, do you want to know?"
"If it has to happen, baby, do you want to know?"
I don't know, I don't know
I don't know, I don't know
But what a line, line, line
What a fucking line, line, line
What a fucking line, line, line
What a fucking line, line, line
What a fucking line, line, line
What a fucking line
What a fucking line
Ruminating, ruminating, now I'm in my head
Ruminating, ruminating all the things you said
Why can't you wait for me to come home? (Come home)
This conversation's too big for a phone call
Ruminating, ruminating, I've been up all night (all night)
Did you kiss her on the lips and look into her eyes? (Her eyes)
Did you have fun? Now that it's done (it's done)
Baby, won't you tell me that I'm still your number one? (Ruminating, ruminating, ruminating, ruminating)
'Cause you're my number one (ruminating, ruminating, ruminating, ruminating)
Ruminating, ruminating, now I'm in my head
Ruminating, ruminating, all the things you said
Why can't you wait for me to come home?
This conversation's too big for a phone call
Ruminating, ruminating, I've been up all night
Did you kiss her on the lips and look into her eyes?
Did you have fun? Now that it's done
Baby, won't you tell me that I'm still your number one?
