My favorite Vocaloid english covers

Kokoro (Shiroko)

I was just a robot that was made
By a smart and lonely scientist
The result could only be called a miracle

There was still something lacking in me
Something that can't be made easily
My creator said it was a heart, a special program

Days turn to months, years have passed me by
I'm all alone with no one by my side
All that is left is just to decide on a wish

I want to know who that person was
And why he did everything for me
Toiling away working hard to make me a heart

Now a miracle begins for me
Working with incredible speed
Why do my tears seem to fall so endlessly

And now why am I trembling like this
I can feel my heart beating fast
Is this what he made for me
My very own heart and soul

Mysteries, in my heart, in my heart, mysteries
Now I can finally see what happiness means to me
Mysteries, in my heart, in my heart, mysteries
Now I can finally feel all of the sadness in me
Mysteries, in my heart, in my heart, again
How deep are these feelings inside of me

Now I finally see why I was born
The reason why you gave me a heart
All alone, brought in this world, I'm by myself

Yes, now on that day and at that time
Memories fill up in my mind
As my heart takes in the pain and overflows

I can finally say real and sincere words
I dedicate this song to you

Thank you so much, thank you so much
For giving me the chance to live in this world with a heart
Thank you so much, thank you so much
For all the days that we have spent together

Thank you so much, thank you so much
You gave me everything that I always needed and more
Thank you so much, thank you so much
I'll sing for all eternity
