Nominations for the ceremony, considered to be the world’s biggest fan-voted award show, were unveiled in full on Monday (Oct. 13). Also, organizers announced Charli XCX would perform for the first time on the AMAs, which will be broadcast live from L.A.’s Nokia Theatre on Nov. 23. ABC will air the broadcast live from 8 p.m. ET. 

This year’s line-up introduces a few changes. The artist of the year category grows from five to 10 nominees, with Iggy facing off against Beyoncé, Luke Bryan, Eminem, Imagine Dragons, John Legend, Lorde, One Direction, Katy Perry and Pharrell Williams for the award. 

Meanwhile, the single of the year category grows from three to five nominees, including Azalea featuring Charli XCX’s “Fancy,” Legend’s “All of Me,” MAGIC!’s “Rude,” Katy Perry featuring Juicy J’s “Dark Horse” and Pharrell Williams’ “Happy.”

AMA nominees are based on key fan interactions as reflected in Billboard Magazine and on Billboard.com, including album and digital singles sales, radio airplay, streaming and social activity.  These measurements are tracked by Billboard and its data partners, including Nielsen Entertainment and Next Big Sound.
