What rock band, fairly new, sings a song which in the chorus he asks the same question "What if I... ?"

Question

It's more like a power ballad.

Melody (beginning of chorus)

la la la, la la la
la la la, la la laaaaa
(instrument)
la la la, la la la
la la la, la la laaaaa

OR

What If I, la la la
What If I, la la laaaaa
(instrument)
What If I, la la la
What If I, la la laaaaa

Answer 1

the kill by 30 seconds to mars

Answer 2

Could be Creed - What If .... but it's not new.

I can't find the rhyme in all my reason
I've lost sense of time and all seasons
I feel I've been beaten down
By the words of men who have no grounds

I can't sleep beneath trees of wisdom
When your ax has cut the roots that feed them
Forked tongues in bitter mouths
Can drive a man to bleed from inside out

What if you did?
What if you lied?
What if I avenge?
What if eye for an eye?

I've seen the wicked fruit of your vine
Destroy the man who lacks a strong mind
Human pride sings a vengeful song
Inspired by the times you've walked on

My stage is shared by many millions
Who lift their hands up high because they feel this
We are one
We are strong
The more you hold us down the more we press on

What if you did?
What if you lied?
What if I avenge?
What if eye for an eye?

I know I can't hold the hate inside my mind
'Cause what consumes your thoughts controls your life
So I'll just ask a question
What if?

What if your words could be judged like a crime?

Answer 3

We need a little more information than that. Do you know any more of the words to the song? It, of course, could possibly be the song that facepeeler2225 (ewww, what a name!) mentioned....in which case, yes, that is not new.
