“Into Dust,” punctuated by a slow, melodic guitar, tells the story of a woman who feels she is decaying and fading away into thin air (as if into dust). She explains to somebody how she feels that she and every other interaction she has with other people disappears into nothing.

The song has been used or referenced in multiple occassions, such as:

Virgin Media’s 2009 ad campaign:

Red Hot Chilli Peppers' “Aeroplane”:

I’m turning into dust again
My melancholy baby
The star of Mazzy must
Push her voice inside of me
