UPDATE: SEE THE FULL LIST OF WINNERS HERE

Taylor Swift's 1989 has dominated the charts since its October release, so it's no surprise that she also leads the just-announced finalists for the 2015 Billboard Music Awards.

Finalists were revealed Tuesday (April 7), starting with the first five categories announced by returning BBMA host Ludacris and Fall Out Boy's Pete Wentz on ABC's Good Morning America. Then Luda's first-time co-host Chrissy Teigen and Empire star Jussie Smollett unveiled the remaining finalists during a Twitter press conference and Q&A.

Following Swift -- who racked up 14 entries in 13 categories -- is Sam Smith (13), Iggy Azalea (12) and Meghan Trainor (nine). Billboard Music Awards finalists are based on album and digital song sales, radio airplay, streaming, touring and social-media interactions -- measurements that are tracked year-round by Billboard and its data partners, including Nielsen Music and Next Big Sound. The awards are based on the reporting period of March 10, 2014, through March 8, 2015.

In addition to this year's 40 chart-specific categories, fans will choose who gets the Billboard chart achievement award by voting on Billboard.com, BillboardMusicAwards.com and on Twitter; Swift, Azalea and Trainor are up for the only fan-voted prize.

The Billboard Music Awards -- produced by Dick Clark Productions -- will air live from the MGM Grand Garden Arena in Las Vegas on Sunday, May 17, from 8-11 p.m. ET on ABC.
