I can only say so-so, right? After all, when you grow up, you have two books. No matter how good your major is, it cannot compare with one. And it mainly depends on individual efforts. Especially music. It is possible to transfer majors, but your grades must be among the top in your major (I forgot the percentage, but you have to study well anyway) before you can transfer. It's okay to find someone to spend the money, but it seems like you can't transfer more than ten or two hundred thousand each.
