There are millions of people that genuinely reject the idea they suffer from normal cognitive biases, or that they can be fooled, and that's a huge part of their worldview, that they are "smarter" than other people because they aren't affected by those pesky "biases". So whatever they "experience" must be ground truth. So if they think the song sounds better under C++, it doesn't matter what "the experts" say, they must be wrong.
