I work with a talented and diligent colleague who started college as a CS major but switched to music (and a minor in geology). He participates in hardware hacking CTFs for fun and runs circles around me. I also work with another colleague who had a scholarship to his undergrad for music, who switched to CS. Not as technical as the first colleague, but is very good at systems thinking. A third colleague is a superb SME who understands security policy, compliance, and risk management (with a CISSP and actually using it); he was an architect and interior designer before switching careers... and is in a band. :) Music isn't a bad background to have in IT or security fields from my perspective. Issues with anecdotes aside, I don't see the issue here if a person has demonstrated growth and expertise in the field.
