This is very true but fortunately for us, programming is a little more scientific and objective than making music. When I find myself unsure which route to take I try to fall back on principles such as DRY and coding at the right level of abstraction. At least with programming, you can go back and say "this is a load of rubbish because of X", or "this is and awesome design because of Y". In fact this is what I try to encourage in my fellow team mates. You shouldn't choose a particular design without knowing exactly why it is the better choice over any other.
