There's often talk of albums and bands, but seldom about "songs" that stand on their own two feet, and can be discussed, praised or simply name-dropped. I have failed to find any thread dedicated to the single track. Obviously, few industrial/noise/P-E tracks lend themselves to humming along in the kitchen, or getting stuck in one's head, but there are quite a few that stick out in one way or another. So, how about we name a few?
The first hit that springs to my mind is Rasthof Dachau "Exitus". I could list many more in short order, though.
