Little Black Sandals has featured on the Grey's Anatomy spinoff (which IMHO is better) Private Practice. In case you wonder where you heard it. The rest of the tracks equaal Sia's debut; in particular the song Academia, which she sings as a duet with Beck.
Lentil is an amazing tune, Electric Bird is solid, if peculiarly named, and You Have Been Loved is beautiful, whimsical, and pretty damn sad.
A fantastic follow-up album which doesn't disappoint!
