Bài hát: Double Rainbow - Katy Perry

You're a one of a one
A one of a kind
That you only once in a lifetime
Made to fit like a fingerprint
A code that clicks open the gold mine

They say one man's trash is another man's treasure
When I found you, it was all pity better

Secretly, I hit the lottery
'Cause you're brighter than all of Northern Lights
You speak to me, even in my dreams
Wouldn't let you go for even the highest price

They say one man's trash is another girl's treasure
So if it's up to me, I'm gonna keep you forever

'Cause I understand you, we see eye to eye
Like a double rainbow in the sky
And wherever you go, so will I
'Cause a double rainbow is hard to find

Words are phenomenon when you came along
Yeah, our chemistry was more than science
It was defining, light like lightning, it was striking
You couldn't deny it

They say one man's trash is another girl's treasure
The two of us together, make everything glitter

'Cause I understand you, we see eye to eye
Like a double rainbow in the sky
And wherever you go, so will I
'Cause a double rainbow is hard to find

To the bottom of the sea, I'd go to find you
Climb the highest peak to be right beside you
Every step I take, I'm keeping you in mine

'Cause I understand you, we see eye to eye
Like a double rainbow in the sky
And wherever you go, so will I
'Cause a double rainbow is hard to find

[Outro]
It's hard to find, It's hard to find
Once in a lifetime
Once in a lifetime
Once in a lifetime
