I can definitely see how it could be about the music industry, but another interpretation, I see it being about people judging a person. Their "song" represent's the person's self as a whole and at the end even goes to say it is their soul. They want to escape the criticism and judgement of everyone and at the end they adopt more of an optimistic mindset that although they can't fit in or escape judgement they will get through it.
