So, tumblr's got some ideas behind the lyrics of the clip of "Gold" that I posted earlier(on this page).
My favorite theory is its from Yang to Ruby, basically saying she'll take care of her. Also, there's the lines,
I will burn like the sun
I will keep you safe and warm
Like the smell of the rose on summer’s day
I will be there to take all your fears away
With the touch of a hand
I will turn your life to gold
With the touch of a hand
I’ll turn your life to gold

So looking at that, burning like the sun comes straight out of Yang's section of I Burn. Turning her life to gold is similar to Yang's Yellow Beauty Burns Gold line, and then there's the interesting bit.
"Like the smell of a rose on a summer's day"
Summer Rose. The name on the tombstone that Ruby was leaning over in the Red trailer.
