Have ya'll heard that Sia interview that she's posted recently.
I think she's throwing a bit of shade at Rih, she's saying that when she heard Rihanna's version of Diamonds she thought it was her
She also says that Perfume, Cannonball were just exactly like her version.
And then she said that Beyonce took 'Pretty Hurts' to a new level, and the song she gave to Adam Lavigne which is coming out soon she said Adam took that song to another place.
But then at the end she said it's a compliment that they copy her singing style, and keep her backing vocals. Also she say's that if a singer records one of her songs, and changes the note she makes them go and 'melodyne' it and change it to the note its supposed to be, or she makes the singer go in and re-record it

So underrated. Deserved so much more than the bonus track treatment.
