Verdict on 11 contenders from songwriter Ester Dean, DJ Zedd, Paramore's Hayley Williams, hitmaker Ed Sheeran
Hayley Williams: I love Q-Tip, I love Fergie. But a little too much of this party might actually kill somebody, and that somebody might be me.
Ester Dean: Did they put ''It don't mean a thing if it ain't got that swing'' in there? I think that feels classic. This is my favorite.
Zedd: Fergie's vocal performance is really solid, besides the part that sounds a little bit like ''Party Rock Anthem,'' but that's fine in this case.
Ed Sheeran: That was quite a surprising one, actually. It kind of has a hint of old-school soul-funk and then just suddenly drops into an EDM tune. I think those songs always do well in summer.
