Way to go, Sheerios! In what might be the closest Pop Clash ever, Ed Sheeran's 'Don't' beat out Katy Perry's 'This Is How We Do' by one vote. What a close race! This week, Ed is up against his BFF Taylor Swift's 'Shake It Off.' Who should win this week's Pop Clash?

With its emotional vocals and straight-to-the-point lyrics, Ed Sheeran's 'Don't' is positively heartbreaking. The track is a bitter reminder of what happens when you stray in a relationship. With its catchy hookup and Ed's dismissive "don't," we can't help but sing along every time we hear this track.

Taylor Swift's 'Shake It Off,' on the other hand, shoos away the haters in peppiest way possible. The singer takes the negativity and brushes it off, refusing to let other keep her down. We love the track's positive message and the song's irresistible energy!

Who should win this week's Pop Clash? You can vote for Ed Sheeran's 'Don't' or Taylor Swift's 'Shake It Off' once an hour until the polls close at 3PM ET on Sept. 2.
