Poem Stories are a bit complex and thus resemble "Poems" to a certain degree. It could be the density of language, the mystery of content, the unusual structure, etc., that might contribute to the sense of these Lyrics being out-of-the-ordinary (or "non-commercial" if you prefer). Of course, I am aware that for song lyrics, this may not be a popular or profitable strategy. But any one of these Lyrics can become unique and memorable in its own way. There are, in fact, plenty of intriguing or enchanting lines/phrases/words in these works that will capture a listener's imagination without question. We will likely have to manipulate or amputate words to create a quality song but it can be done as long as this corresponds to the path of your artistic journey.
