This is a pretty fair comparison. Music has a pretty standardized format, relatively speaking, in what 'sounds good' and what sounds 'bad' based on one's cultural upbringing. As in, certain tonalities are pleasing to the ear. From basic understanding and competency comes the ability, in theory, to 'compose' pieces. My experience with coding is similar in that there are good ways to structure a composition, and not-so good ways. In coding, a compiler or testing the program is what reveals if something works or not, much in the same way that playing back a recorded version of a composition can reveal what's good or not good about a musical piece.
