If I were to major in music....

what sort of options would I have as far as a career choice? I love playing music and being a part of it, but I have no idea where to go regarding a career. I've always just considered this my most passionate hobby, and at the moment I am not focused on music as a major but I am starting to wonder if it is the only real way to go for me. For people who have been through this same situation or just know a lot about where the money is at in music related jobs, what are my options? Also, if you are involved in music as a career how do you feel about it now that you've been at it for some time?
