Who sings this song?!

Who sings this song?

Theres this song I think these are the lyrics:(in quotes)
something about Firewalls or something, then its like "Facing against the glass thinking about, ooh. wide open spaces in between. all I want it to" something. I think it might also say something about "green pastures" but I am not sure

I think you are looking at the song "Wild Horses" by "NATASHA BEDINGFIELD"

Ooooh

I feel these four walls closing in
Face up against the glass
I'm looking out, hmmm
Is this my life I'm wondering
It happened so fast
How do I turn this thing around
Is this the bed I chose to make
There's greener pastures I'm thinking about
Hmm, wide open spaces far away

All I want is the wind in my hair
To face the fear but not feel scared

wild horses I wanna be like you
Throwing caution to the wind, I'll run free too
Wish I could recklessly love like I'm longing to
I wanna run with the wild horses
Run with the wild horses, oh

whoahh Yeah, oh oh, ye-yeah

I see the girl I wanna be
Riding bare-back, care-free
Along the shore
If only that someone was me
Jumping head-first, head-long
Without a thought
To act and DAMN the consequence
How I wish it could be that easy
But fear surrounds me like a fence
I wanna break free

All I want is the wind in my hair
To face my fear, but not feel scared

Oooh, wild horses I wanna be like you
Throwing caution to the wind, I'll run free too
Wish I could recklessly love like I'm longing to
I wanna run with the wild horses
Run with the wild horses, oh

I wanna run too
Oooh oh oh oh
Recklessly abandoning myself before you
I wanna open up my heart
Telling how I feel, ooh ooh

Oooh, wild horses I wanna be like you
Throwing caution to the wind, I'll run free too
Wish I could recklessly love like I'm longing to
I wanna run with the wild horses
Run with the wild horses
Run with the wild horses

Ooh ooooh ooh ooh ye-yeah yeah oohh

I like the "Unwritten" song, got a good beat but never heard this one though.
