You got it. The real issue with forced-choice blind listening tests using music, IMO and I've studied them, is that they've never been scientifically validated and no one knows how sensitive (or insensitive) the tests are.
They appear to be more of a test for the listener than for differences between components, because unlike the medical trials DBTs were designed for, listeners' results improve with training. Medical DBT results don't change with experience.
Tasting wine blind is just like listening to two components blind (with no X to be forced to chose)- you may be surprised by the qualities you identify - and what you like.
