Yes, I tend to make such mistake, because I don't really deal with vocals at all.

For this reason it's hard to rely on this kind of feedback. Scientist now say that people can't really tell what they are thinking, because most of the thinking is a background process. Mostly they tell some cliches which more or less suit a context.

Well, the point is that the final audience will hear it in their own, intuitive way; and the process of creating such a thing is also mostly intuitive. I believe that you will process the feedback here in a right and careful way, with an amount of scepticism.
