Kilogram by The Doubleclicks Lyrics

It started physical but there's no shame there
I was what you needed and I was happy to stay there
You said I was your constant, your ideal
And I started to think that the thing we had was real

The days turned to years right in front of our eyes
You kept me locked up here, I felt like a prize
You said I was the best you’d had and I clung to your word
I wanted to be what you needed, for you I was standard

I was lost for so long but you showed me who I am
I would never be wrong if I was your kilogram

But now it's all over if your calculations are correct
I'm more than a number and that is why we are wrecked

I know it makes sense
I know you have needs
But what do I do now
What about me
Could you really replace me with nothing but numbers?
I suppose that you can
But who will I be if I’m not your Kilogram

I’m searching for meaning
In your eyes but they’re blank
There is someone else, I know it
Somebody named Planck

I know it makes sense
It’s logic, it’s smart
But I did nothing wrong
Do you not have a heart

Would you let a committee of strangers tell you who I am?
And will you really be you, without your kilogram?
