Last week, Taylor Swift ousted Miley Cyrus' 'Wrecking Ball' with almost 2/3 of the vote! As the new Pop Clash champ, can 'Everything Has Changed' hold the title against Kelly Clarkson's 'Tie It Up'?

When it comes to writing a love song, no one conveys falling head-over-heels better than Taylor Swift. With 'Everything Has Changed,' T. Swift zeroes in on love at first sight, with the help of Ed Sheeran. Swooning over just knowing that special someone's name, she promises that from here on out, her life will be different. Awww, so sweet!

Kelly Clarkson is a Southern girl who isn't afraid to speak her mind or go after what she wants. When she found her other half, she was all about putting a ring on it. 'Tie It Up' is the peppy, anthem of a relationship progressing from the first date to locking it down. (Her term, not ours!) Kelly's enthusiasm is totally adorable -- and relatable!

Who should win this week's Pop Clash: Taylor Swift or Kelly Clarkson? You can vote once per hour until the poll closes at 3PM ET on Sept. 30.
