[Verse 1]
You’re like a junk email in my inbox
You keep coming back, keep coming back
Like a constant ringing in my ears, oh
Keep calling back, why are you calling back again?

[Verse 2]
Like a train that’s running out of steam, oh
You’re losing track, should’ve stopped way back
You’re with a new girl now, she’s only 16
Hanging from a string, I hear her heart smash

[Pre-Chorus]
So tell your girlfriend
You used to be my boyfriend
Used to be my boyfriend
How would she like that?
She doesn’t know about all the things you done then?
All the things you said?
Just to try and get me back
But you had your chance

[Chorus]
Peroxide, on your heart
It’s burning, it’s falling apart
Peroxide, on my heart
It’s turning, light from the dark
Peroxide, in your eyes
It’s burning, burning your heart
Peroxide, as you ask why
You ask why it all fell apart
[Verse 3]
She’s the one beautiful rose in a thorn field
But she doesn’t know, that you’re among those
She can only give so much until you take
Take yourself back and leave the pain

[Pre-Chorus]
So tell your girlfriend
You used to be my boyfriend
Used to be my boyfriend
How would she like that?
She doesn’t know about all the things you done then?
All the things you said?
Just to try and get me back
But you had your chance

[Chorus]
Peroxide, on your heart
It’s burning, it’s falling apart
Peroxide, on my heart
It’s turning, light from the dark
Peroxide, in your eyes
It’s burning, burning your heart
Peroxide, as you ask why
You ask why it all fell apart
[Bridge]
Let it burn
Cause it’s your turn, to feel something now

[Chorus]
Peroxide, on your heart
It’s burning, it’s falling apart
Peroxide, on my heart
It’s turning, light from the dark
Peroxide, in your eyes
It’s burning, burning your heart
Peroxide, as you ask why
You ask why it all fell apart
