Wow first hilde45 wants to pretend he doesn't understand the difference between liking a song and thinking it is a demo track, then Rick wants to pretend he doesn't know ;) is a wink and means, "kidding"!
It’s merely good scientific method to reject the pretense that a test
can pretend to be more than what it is. But that doesn’t mean such tests
don’t have any value -- only that their value needs to be specified in a
proportionate way relative to the overall experimental question.
It may have been heavily encoded
I'll say! Can you run that one through your decoder ring, please? ;)
