I don't really see it. Wolf is a pretty good song vocally but, outside of that, all other aspects are way toward the bottom of the black album's barrel imo.
Riffwise, I feel it only beats Sad and Tread. The solo may be the worst on the entire album since, oddly enough, that's one of the few areas where Tread doesn't suck more than all other songs. Bass isn't really audible enough on this album for it to be a real factor from song to song (more audible than Justice though at least.) And drums are basically a wash since this album, as a whole, more or less marked the death of Lars giving a shit.
