The meaning(s), or lack thereof, ascribed by others to an example of lyric work are not part of the work. The interpretations are separate "works". The manner in which an audience receives the work, what they, collectively and individually, make of it, can indeed provide potential data for the allusiveness (referentiality)of future lyrics, gainsaid, but cannot be ascribed as a characteristic of the particular work, per se, with validity without "insider information" which is, in any case, no part of the song. That way lies true nonsense, even unto deconstruction. Yet the little bugger of a jingle persists and seems to move hearts.
