14. 'Buttons'

We begin with Hilarious Sia™ (as opposed to Sombre Sia™ which, rest assured, follows next). Some Sia videos are unadulterated lessons in lolz and this one is an instance in point. It was a kind-of single which ended up tucked at the back-end of 2008's album, Some People Have Real Problems, as a bonus track and it therefore tends to be unjustly overlooked. There's a good CSS remix knocking about on the internet if you're interested but, as is often the case, it's the original version that's worth the dollar.
