No surprise here: With three awards, Taylor Swift proved to be the big winner at last night's (November 22) American Music Awards. But the show's performers—who delivered through fire and rainfall, alike—were likely the center of water-cooler conversation this morning.

Host Jennifer Lopez kicked off the ceremony with a song-and-dance medley that featured some of the year's biggest hits including "Uptown Funk," "Bad Blood" and "Anaconda," and the energy didn't wane. With powerful vocals from Demi Lovato and Carrie Underwood, sharp choreography a la Justin Bieber and raw emotion issued by Gwen Stefani and Celine Dion, the AMAs had a little something for everybody. But which was the performance you considered most memorable?
