Passive Voice at Song:

Linkin Park-Numb

Lyrics
I'm tired of being what you want me to be (Passive Voice)
Feeling so faithless, lost under the surface
Don't know what you're expecting of me
Put under the pressure of walking in your shoes
(Caught in the undertow, just caught in the undertow)
Every step that I take is another mistake to you
(Caught in the undertow, just caught in the undertow)
I've become so numb, I can't feel you there
Become so tired, so much more aware
I'm becoming this, all I want to do
Is be more like me and be less like you
Can't you see that you're smothering me?
Holding too tightly, afraid to lose control
'Cause everything that you thought I would be
Has fallen apart right in front of you
(Caught in the undertow, just caught in the undertow)
Every step that I take is another mistake to you
(Caught in the undertow, just caught in the undertow)
And every second I waste is more than I can take
I've become so numb, I can't feel you there
Become so tired, so much more aware
I'm becoming this, all I want to do
Is be more like me and be less like you
And I know I may end up failing too
But I know you were just like me with someone disappointed in you
I've become so numb, I can't feel you there
Become so tired, so much more aware
I'm becoming this, all I want to do
Is be more like me and be less like you
I've become so numb, I can't feel you there
I'm tired of being what you want me to be
I've become so numb, I can't feel you there
I'm tired of being what you want me to be


Carrie Underwood - Inside Your Heaven


Lyrics

I've been down (Passive Voice)
Now I'm blessed
I felt a revelation coming around
I guess it's right; it's so amazing
Every time I see you I'm alive
You're all I've got
You lift me up
The sun and the moonlight
All my dreams are in your eyes
And I wanna be inside your heaven
Take me to the place you cry from
Where the storm blows your way
And I wanna be the earth that holds you
Every bit of air you're breathin' in
A soothin' wind
I wanna be inside your heaven
When we touch, when we love
The stars light up
The wrong becomes undone
Naturally, my soul surrenders
The sun and the moonlight
All my dreams are in your eyes
And I wanna be inside your heaven
Take me to the place you cry from
Where the storm blows your way
And I wanna be the earth that holds you
Every bit of air you're breathin' in
A soothin' wind
I wanna be inside your heaven
When minutes turn to days and years
If mountains fall, I'll still be here
Holdin' you until the day I die
I wanna be inside your heaven
Take me to the place you cry from
Where the storm blows your way
Wanna be inside
Where the storm blows your way
I wanna be inside your heaven
Take me to the place you cry from
Where the storm blows your way
And I wanna be the earth that holds you
Every bit of air you're breathin' in
A soothin' wind
I wanna be inside your heaven
