The Weeknd and Pop Smoke were among the early winners at the Billboard Music Awards.
The ceremony, which celebrates chart success, took place at the Microsoft Theatre in Los Angeles and was hosted by Nick Jonas.
Canadian R&B star The Weeknd led the way in nominations with 16 and picked up the first televised award – for top hot 100 artist – and in his acceptance speech said “it’s been a dark year”.
He also joked about not having to wear the red suit that has become synonymous with his chart-topping album After Hours.
Jonas described the last 12 months as “an insane rollercoaster ride” before explaining the masked, in-person audience was possible due to following pandemic safety guidelines.
Producer DJ Khaled opened the show with singer-songwriter H.E.R. and rap group Migos, performing their collaboration We Going Crazy.
Doja Cat and SZA were also among the early performers with their song Kiss Me More.
