Last night during American Idol, a V for Vendetta teaser trailer ran. 
It was pretty short but had a very cool song in it, it sounded almost
like Sarah McLaughlin, but apparently it's not her.  It goes "You'd
better run, run run, run run, to me... You'd better run, run run, run
run to me."  and I can't find it anywhere.  Can you tell me what the
name of the song is and who performs it?

Hello

I believe the nameof the  song is ?I Found A Reason? by CAT POWER.

Lyrics

?Oh I do believe
In all the things you say
What comes is better that what came before

And you?d better run run, run run to me
Better run, run run, run run to me
Better come, come come, come come to me
You?d better run?
