The music industry has a tendency to paint a false dilemma concerning art versus commerce. If you consider that a lot of the biggest-selling music since the sixties has been, in fact, conscious music, the truth becomes clear that the growing absence of conscious music in pop culture has less to do with lack of demand and more to do with lack of quality decision-making at record labels.
Conscious music is innovative art, and innovative art sells if it's good enough. The idea that every possible melody or storyline has already been written is just a cover for lack of imagination. This false idea is also fueled by those industry gatekeepers who try to keep shallow trends moving, even when they start to burn instead of earn money. The truth is that there are infinite possibilities for songwriting.
