歌曲歌词：
Do you see the ashes dancing
Since nobody ever care
Will they fly will they rest where will they be
And though I got nothing
Still I wish you were there
So I finally
Can't stop finding you
But I was wrong
You rise me up
Out in the dust
Never falling apart
Oh I was wrong
Please don't conceal the pain
I'm always here
To heal you and love
There is time for us to waste
Like the ashes in the wind
Will they leave will they stay where will they be
I know it's hard to give
Give all your love with no repay
But you finally
Give me everything
But I was wrong
You rise me up
Out in the dust
Never falling apart
Oh I was wrong
Please don't conceal the pain
I'm always here
To heal you and love
Even when the rain has come to me
I still believe
One day gonna be fine
I'll be there for you
I am not alone
When you hold me
Out in the dust
Never falling apart
So open up
Please don't conceal the pain
I'm always here
To heal you and love
Wish I could be with you
