With respect to the Forbes article, some good schools for you definitely have been included. Some of the methodology, however, appears based on preferences. For example, would it be important to you to study with lots of other international students (a factor in the methodology)? If you would like to study in the U.S., then in my opinion you should be comfortable studying with U.S. students, and a factor such as the percentage of internationals should be considered lightly. Additionally, many elite U.S. colleges do not offer business majors, but since Forbes concluded internationals often study business, this was another factor in the methodology. Nonetheless, the article seems to be a great source for further ideas. I’d only recommend you don’t limit yourself by it.
Regarding music / music theory, you should be able to find excellent opportunities for this as a minor, as well as in your collegiate ECs.
For now, based on aspects of what you’ve posted, I’d strongly recommend you research Hamilton, URochester and Grinnell. These schools, though similar in some ways, cover a range in atmospheres and selectivity that could gain you a desirable, affordable admission. Consider lots of other colleges as well (including those in your original post), of course, but this group could offer you a desirable base on which to build.
