I’d advise you to go for what you love but have a backup plan. That’s what I did. I graduated with my music degree and I am still active free-lancing and playing for church, but it wasn’t enough to survive on. So I went back to school for my nursing degree, which has offered me a great amount of flexibility. The job opportunities in music therapy are quite limited and the pay is very modest, especially considering the amount of training required (college degree plus internship). I worked in a VA psychiatric hospital some years ago, and the music therapists were at about the same pay grade as the licensed practical nurses, whose training program is less than a year!

Let’s hope they have upgraded their pay in the years since, but I wouldn’t bet on it.
Some people are interested in music therapy, but don’t really know what music therapists do. The best way to find that out is to see if you can spend a day or two following a music therapist around on the job, or at least interview one in person. The only music therapists I have ever encountered have worked for psychiatric hospitals, so that would be the first place to look. Obviously, if you have no interest in working in a psych hospital or long-term care facility, you should consider something else for your career.
If you are interested in education, you could major in foreign language and minor in music (or vice versa) and be able to teach in both areas.
Most of all, pray. God will guide you.
