Do you think this is a subversion thing or Subclipse....

Thanks

"Fade To Grey"
It's not hard to know what you're thinking
When you look down on me now
Your trance of love is seeking
To turn this world around
But in my state of blind confusion
No God can pull me out
I see your love is willing
To turn me inside out
And then I see you there
The lonely tears I cry
I wish they'd release me
It's in despair that I find faith
Summon the night to bow down to day
When ignorance is bliss
Save me from myself
[Chorus:]
And then I see You there
With Your arms open wide and You try to embrace me
These lonely tears I cry
They keep me in chains and I wish they'd release me
Cold is the night but
Colder still is the heart made of stone, turned from clay
And if you follow me
You'll see all the black, all the white fade to grey
Fade to grey
Fade to grey
