I can't decide on a major. Any help or tips?

I have just completed my first year of college and have already changed my major 3 times. I absolutely love music for I have been a musician since I was 11 and I am now 20. As of now I am a Music Industry major and a Mathematics Minor. Here's the predicament: My girlfriend and I want to move to the UK after we get married in about a year. My university offers a few online Bachelor's degrees, but not Music industry, nor mathematics. If we moved then, her bachelor's degree and our combined salaries could get us the HSMP visa, but I would have to drop my Music Industry major and Math minor to settle with a computer science major and most likely a political science minor to get my online degree. Here's the reason I think I may change to that anyways: J-O-B-S. I've already searched for jobs under music industry and radio broadcasting in both the UK and the US, and I have pretty much come up empty handed. There are none. This has convinced me to consider changing my major to CS and my minor to Political Science or something similar. I don't really want to because my dream has always been to get out of college and go to work for a recording company as a producer or sound engineer. It sucks, but jobs are scarce, and I may be forced to change my major just to find a job in the future. I can always change it, work, suffer, and then go home to my wife, guitar, drums, recording equipment, and band and live the life I want out of work (lol). Anyways, any tips or advice would be greatly appreciated. Thanks.
