It's been too long.
So I decided to go a little old school.
This song was the 2nd single from her 2008 studio album Some People Have Real Problems. Seeing that album displayed for sale at my local Starbucks was my first introduction to Sia. Of course, I didn't actually hear her until years later. And it is, of course, fantastic pop music that was criminally overlooked in this country, and really around the world.
No wonder she retired!
Also, notice that Sia is facing the camera - a lot! and smiling - and not relying on Maddy Ziegler as a stand-in. That whole stage-fright assumption is a bunch of crap.
