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
