The "6 minutes soundtrack" at the very end of "Six Feet Down". Particularly like it because it fitted that wonderful endsequence so well. Listening to other stuff by Sia, and it's not bad.
update
Songs are different enough, trip-hoppy beats, slow/fast, almost close-harmony singing.
update 2
compare from "Healing is difficult" the songs George Michael-ih "Blow it all away" and the dance-track "Untitled": "I drink booze to open up my mind"
