You're like a junk email in my inbox
Keep coming back, you keep coming back
Like a constant ringing in my ears oh
You keep calling back, why are you calling back again You're 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 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've done then
All the things you've said just to try and get me back
But you had your chance Peroxide on your heart
It's burning, it's falling apart
Peroxide on my heart
It's turning light from the dye
Peroxide in your eyes
It's burning, burning your heart
Peroxide, you ask why
You ask why it all fell apart She's one beautiful rose in a thorn field
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 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've done then
All the things you've said just to try and get me back
But you had your chance Peroxide on your heart
It's burning, it's falling apart
Peroxide on my heart
It's turning light from the dye
Peroxide in your eyes
It's burning, burning your heart
Peroxide, you ask why
You ask why it all fell apart Let it burn 'cos it's your turn
To feel something now Peroxide on your heart
It's burning, it's falling apart
Peroxide on my heart
It's turning light from the dye
Peroxide in your eyes
It's burning, burning your heart
Peroxide, you ask why
You ask why it all fell apart
