@DJDarren A second #AusMusic suggestion on the theme "Underworld" is

Shooting Stars by Bag Raiders.

How does it fit?
1) Well being "down under" (both in location and musical selection) everything is in reverse, so your underworld is my space.
2) As the meme this song spawned demonstrates, you spin around every which way in the ether, and that's very underworld'ish.
