Sia Does A Really Amazing Version Of Rihanna's "Diamonds"

Sia cowrote the song, so it's not too surprising that she sounds incredible singing it herself.

At the Norweigan-American Achievement Award ceremony yesterday in Sweden, Sia explained how she co-wrote Rihanna's hit "Diamonds" with Benny Blanco — in just 22 minutes — and recorded the full demo with the famed duo from Stargate in another 26 minutes. Stargate's Tor told the crowd, according to YouTube, that "she had her coat on and her bag in her hand, and a car waiting downstairs to take her to the airport!"
