Whew. This was a close one! In last week's Pop Clash, Ed Sheeran edged out Nicki Minaj by one percent. This round, the singer's 'Don't' is up against Hilary Duff's 'All About You.' Which song should win the Pop Clash?

Ed's 'Don't' is a bitter reminder of the heartbreak caused by cheating. Although the listener knows the outcome of the song isn't a positive one, Ed's narrative lyrics are still entrancing. 'Don't' is honest, catchy and an instantly iconic track from the Brit.

Speaking of catchy, we can't stop listening to Hilary Duff's 'All About You.' The folk-rock vibe is completely different from her traditionally straight-up pop music, but Hilary totally works it. It's a sassy tune -- Hilary saucily makes a reference to the mile-high club! -- but it brings a maturity that the singer didn't have on her last album.

Which track should win this week's Pop Clash? You can vote for Ed or Hilary once an hour until the polls close at 3PM ET on Sept. 15.
