You assume entirely too much. At the web development company I work with, at least 3/4 of our company are or were gigging musicians at some point, and go to shows, and could all likely rattle off answers to your questions. Our main product is an eCommerce system, so it's not like I'm working at CDbaby or something.

Programmers and musicians both do a lot of pattern recognition, and I've found a lot of crossover between the two.
