It's almost time for the 2019 Billboard Music Awards!

Kelly Clarkson, who is hosting the award show for the second year in a row, announced a few of this year's nominees along with Dan + Shay during Thursday's episode of Today.

So, how are the nominees selected? Well, there are a lot of factors. According to Billboard, the finalists are determined based on key interactions with fans, album and digital song sales, radio airplay, streaming, touring and social engagement.
