I've worked with several senior people ("Principal Enterprise Architect", etc...) who were music majors, and as a rule they were terrible at their jobs. They just... didn't care about anything even vaguely related to computers. Without exception they got into their positions through nepotism, ass-kissing, or dirty politics. None got there through talent.
People who like computers do it as a hobby. They learn programming at a young age, they get a CS degree or a hard science degree, and then they spend their spare time on tech forums like HN.
People who don't like computers play music, learn painting, or do something else. They get degrees in the arts or humanities. They spend their spare time playing music at the local pub, or whatever.
PS: One of the worst programmers I had ever met is also one of the best musicians I had ever met.
