These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: While the rest of the film is a mess, with some decent special effects, perhaps the best part of it would be the energetic and memorable score by Toshiyuki Honda, who would later score the Metropolis (2001). The main theme is pretty good, and the two vocal songs by Mariko Nagai are also very nice and well-done.
Narm: The valuable element is called "texmexium"... as in "Tex-Mex", a type of American/Mexican cuisine.
Narm Charm: the baseball theme playing while Gunhed drives down the walkway (or driveway?).
