The winners will be determined by fan interactions such as album and digital song sales, streaming, radio airplay, and social engagement. Billboard crowns the victor after analyzing chart information from March 21, 2020 through April 3, 2021, making it a strictly number-based competition. So, whether something that may be deemed as better quality than the other may not win based on better sales.
The 2021 Billboard Music Awards air live from Los Angeles on May 23 at 8:00 p.m. EST.
