Through two weeks so far, Carrie Underwood is an unstoppable force. She wins her second week of "Pick the Hit" voting in blowout fashion, easily outdistancing Brad Paisley in last week's round.

Carrie's new single "Smoke Break" received just over 93% of the vote over Brad's newest, "Country Nation." We don't think Brad has anything to really worry about, his new offering is sure to be a hit too, but for now Carrie is the undisputed queen of the contest.

So now Carrie will take on a third challenger, and this time around it's Tim McGraw. Tim's newest is called "Top Of The World." Listen to both songs and vote for your favorite below. We'll reveal the winner of this round on Monday, September 14.
