Recycler Attack!
If I recall correctly, I reused the melody from Nattering Nanites for an EDM-y track.

Recylers are dog-like robo-critters in my fictional world. They cleanse worlds before colonization.

The people on those worlds generally object to being cleansed. Nobody likes the Bulwark, for good reason.
