This thread certainly took a turn for the worst.
More on the point, though, I'm curious as to why its so specifically Bach. The previous example I had made was to demonstrate that, given a near identical style and no name, it wouldn't exact the same ire. The machine example was a musical form of the Turing test, a way of showing that, given the same formula as the real thing, a point is eventually reached where no distinction can be made.
I also wonder if, given a Bach piece obscure enough to him (chances are that something in the 1000s or first few hundred of the BWV wouldn't be familiar), would Rach hate that piece, if unaware it was Bach? I sincerely doubt it would be very easy to glean the composer by ear.
On a similar vein, I'd assume Rach would like something from the over 1000 works of Bach. Even a tune whistled would be something. I state this because I don't like Mozart, Alkan, and Brahms, yet I like at least one piece from each of them (The Requiem, Comme Le Vent, and Wiegenlied respectively).
