'Pretty Hurts' And 14 Other Songs You Didn't Know Sia Wrote

The World Cup song? She co-wrote that too.

With Sia's new album 1000 Forms Of Fear, out yesterday, we have 12 new tracks from the Aussie songwriter herself. But even though Sia (last name Furler) has a chunky discography of her own, she's made quite a killing writing for other people.
