Time Machine SNSD ~ English Version por Kesha

I'm waking up without tu here
It's sinking in so loud and clear
It's over, guess it's over

Wish I could take it back
And find a gun, carry one
And do what's done

It's no redemption for me
Now i've written in this story
One mistake that one regret
One memory I know we can't forget

I'm a prisoner and there's no way out
Cause the future's past
I'm stuck in here now

No time machine
Could ever bring us back
And no apology
Is gonna get this on track

I could play it around
For a thousand years
But that will never change
'Cause nothing's gonna bring us back ~> All <~

I need a time machine
Ooh, I need a time machine

Across the line, a broken room
I hate my self for hurting you
My conscience weights so heavy
Like a boulder since tu left me

Even tought tu kissed me
I gotta let tu go, I'm fallin' to pieces
That tu wont even know
The pain inside is seeing me alive

Just one mistake, just one regret
One memory I know tu can't forget

No time machine
Could ever bring us back
And no apology
Is gonna get this on track

I could play it around
For a thousand years
But that will never change
As if I'm gonna bring us back ~> All <~

I need a time machine

The fastest there's ever been
So I could get tu back with me
Rewind that all in the past
Never wanted anything so bad

I cannot mover on
Cause now that my future has become your past

No time machine
Could ever bring us back
No apology
Is gonna get this on track

I could play it around
For a thousand years
But that will never change
As if I'm gonna bring us back ~> All <~

If only I could change it
If only i could bring us back
I need a time machine
Oh, give me a time machine
Oh, give me a time machine
