Should I stay in the music area?

The music industry is changing, and maybe that means the chances of success are growing, but it seems like it is a risky idea to stay in music, rather than go to the safe engineering route. I could hedge by teaching music, but I'm a song writer, and that is what I want to do. What do I need to succeed in a business that is really only stacked for the few, the lucky or the connected? Or, will Indy music make it less risky, and why?
