Diamonds used to be coal
Look young cause they got soul
And my heart used to be cold
Til your hands laid on my soul
I'm not wondering why
The sky's blue, that's not my business
All I know is
I Look up and tell myself
Be patient...
Enjoy a song
That's why they're beautiful
Baby that's why you're beautiful
That's why they're beautiful.
