Billboard Music Awards Best & Worst Moments: Mariah Hits a Low Note, Kanye Goes Up in Flames and More

You can’t have a music-related awards show without a few key components: Taylor Swift rocking out to every performance from her front-row seat, an ear-splitting shriek from the crowd at every mention of One Direction and, naturally, a few presenters who have no business being there.

Fortunately, ABC delivered all that and more during its broadcast of the Billboard Music Awards on Sunday, and we’ve rounded up all the highlights — for better or for worse — from the three-hour show.

Among the standout moments from this year’s festivities: Mariah Carey’s career-spanning performance (we’ll let you have the last word on that one), host Chrissy Teigen’s show-opening wardrobe malfunction, a rockin’ homage to The Breakfast Club and Kanye West’s fiery closing medley.
