Hey!
I'm a pure music graduate and I did the opposite to what is expected in my college(which is in Ireland btw), I transferred over from a double honours degree to a single honours in Music. I am hoping to train as a music teacher and try and reform the attitude to music education in Ireland later on in my career. But I do not regret, not to say that I don't ever think at times would I have been better off not switching, studying just music. When I came down to deciding where I wanted to have a career, I always knew music had to be a part of it. I'll never be a professional musician, I aspire only to be the best amateur one within my capabilities. I took up piano when I fifteen and I'm still trying to finish my grades. It's tough work and tougher still when you're your only main support structure to get practise done.
So, my opinion, if you really want music as a career, try and figure what type of music career you want and do everything you can to achieve your goals. But never lose sight why you wanted it in the first place.
Just for me personal, I interested in the psychology of music area because music, through listening and now playing has and still does helps me through really bad moments in my life. But that's just me.
