Okay. It seems to me that you've provided a list of differences between tech and music and on this basis say it's a bad analogy. But analogies are by definition a partial resemblance. The point of an analogy is to make a comparison on a relevant dimension. The relevant dimension here is what my GP post tried to explain. Phrases like "no guarantee" also seem beside the point. Nothing is a guarantee of anything in this context. We're talking about factors that influence things.
