[Chorus: phem]
Some days, I feel like I let myself down
I love my life, gonna run it in the ground
Can't sleep for days, got your name in my brain
Can't sleep for days, gotta stay up, stay up forever.

[Verse 1: Machine Gun Kelly]
I'm writing this at 5:3666 in the morning
Wide awake still, not even yawning
Not even sure why I'm up at dawn like I'm celebrating
When my agent told me that no one's calling
It's a ounce in my living room on the couch
Next to a couple homies that smoked it and passed out
So I'm alone with my thoughts in this glass house
In the cabinet are glass vials, I just poured all the last out
I smelled her, now she's on my mind
I met her the first time my light turned lime
Hate it when she's gone, but she ain't hard to find
Left her on my desk, she made designs in little lines.

[Pre-Chorus: Machine Gun Kelly]
It's 5:3666
It's 5:3666.

[Chorus: phem]
Some days, I feel like I let myself down
I love my life, gonna run it in the ground
Can't sleep for days, got your name in my brain
Can't sleep for days, gotta stay up, stay up forever.

[Verse 2: Machine Gun Kelly]
Ayy, look, I'm writing this at 5:3666 in the evening
In my head, talking to these demons (Demons)
In my bed, staring at these ceilings
I just bleached my hair and changed my whole appearance
I'm just fed up with these smoke and mirrors
My uncle sold some pictures of me with no clearance
What the fuck is family? I can't take that serious
Thank God everybody sucks so I can write these lyrics
Go pick her up, I need to lift my spirits
They don't know that we hook up, I don't let cameras near us
There's some shit I do, when she's around, I shouldn't share
Like that week I spent locked in a room with her in Paris (Fuck)

[Pre-Chorus: Machine Gun Kelly]
It's 5:3666 (Yeah)
It's 5:3666.

[Chorus: phem & Machine Gun Kelly]
Some days, I feel like I let myself down
I love my life, gonna run it in the ground
Can't sleep for days, got your name in my brain (Name in my brain)
Can't sleep for days, gotta stay up, stay up forever.

[Outro: Machine Gun Kelly]
It's 5:3666 (Yeah)
It's 5:3666 (Man)
It's 5:3666 (Yeah)
Somebody, tell me why I'm still awake
It's 5:3666.
