I'm not sure from the song what time Mound is from, because he seems to understand science but not have heard of music notation. I was thinking that Mound might be a time traveller which has gotten lost from his own timestream.

Not that I'm all that bothered, I think it stands by itself. I was reminded of the fabled time-and-motion analyst who went to a symphony concert and reported back on all the 'wasted' effort (too many musicians playing the same tune, repeats wasting time, etc.) completely missing the point, and similar sorts who don't understand any reason for fiction.
