Lots of schools have music business. If you can afford it, NYU is a great choice. If you are undecided about the artistry focus versus business, I personally think you can pick up on the business end in other ways, by taking courses, interning, volunteering, and working.
It sounds like you are not a good fit for a BM degree environment since you may switch paths and study something else. Have you looked at Northeastern?
