One thing that comes to mind is ethnomusicology. Ethnomusicologists do all kinds of different things, but, in general, ethnomusicology involves studying music and society. For example, I know somebody who studies how marching bands in New Orleans schools affect the quality of schools. I know somebody else who studies the music of Dave Brubeck and his life. In general, ethnomusicology is when you listen to and focus on music but also connect it to society and culture and write about it. You would need to go to graduate school to do this.
I'm sure there are other careers, but I can't think of any more right now. Good luck!
