Lyrics:

Thousands of hairs
Two eyes only
Its you
Some skin
Billions of genes
Again its you
XX XY
That's why it's you and me
Your blood is red
It's beautiful genetic love
Biological
I don't know why I feel that way with you
Biological
I need your DNA
Your fingerprints
The flesh, her arm, your bones
I'd like to know
Why all these things move me
Let's use ourselves to be as one tonight
Apart of me would like to travel in your veins
Biological
I don't know why I feel that way with you
Biological
I need your DNA
