There were a patience-testing 19 performances - including a weird a capella rendition of the Star Wars theme. But some of them were actually worth watching. These are they.
Ariana Grande - Focus
The best vocal performance of the night - on a cabaret version of Grande's hit single. Bonus points for her grandmother Marjorie, who can be seen dancing in the audience.
Coldplay - Adventure of a Lifetime
In which Chris Martin is surrounded by dancing gorillas.
Selena Gomez - Same Old Love
The dancers do all the heavy lifting here, but the song is still a corker.
Alanis Morissette and Demi Lovato - You Oughta Know
Giving the censors kittens, here are two of pop's fiercest ladysingers with a gutsier version of Adele's Someone Like You.
Justin Bieber - Justin Bieber Medley
Thankfully, it's only a medley of the recent, good stuff. The acoustic version of What Do You Mean is superb, and then you get the chance to see Bieber being waterboarded. Bonus!
PS: Sorry for the Coldplay video auto-playing. If anyone knows how to fix that, message me on twitter.
