OMG it's official now!
I'm so happy for Sia and to think she even considered retiring from music and other quite sad stuff (like committing suicide). I'm glad life has given her a second chance. Sia is a talented singer, composer and songwriter and she is also an incredible human being. I'm definitely stanning for the Queen of Australia.
Cheap Thrills is already my favourite number one hit on BB of the year (if I exclude Hello as the song was released in October 2015).
Btw, when was the last time that someone over 40 topped the Billboard Hot 100?
