2014 Billboard Music Awards

Imagine Dragons won five awards, including top Hot 100 artist for songs' chart performance, top rock artist and top duo/group among others. The Grammy-winning Las Vegas band also performed their song "Tiptoe" on the show.

R&B singers Thicke, Pharrell Williams and rapper T.I. scored four wins on the back of their megahit "Blurred Lines," including awards for top Hot 100 song, digital song and radio song and R&B song.

Seventeen-year-old pop sensation Lorde, dressed all in black with black feather fringes, captured the award for top new artist and top rock song for the hit "Royals," which already landed her two Grammy Awards this year.

The teen, who has also won fans with her thoughtfulness and upending traditional standards of Hollywood beauty, said she was grateful to be able to mature in the spotlight and for the "dialogue around my work and myself."

The Billboard Music Awards - which measures honors by sales, radio airplay, touring, streaming and other metrics - is a top venue for artists to unveil new songs in time for the summer.
