No it doesn't. Why can't you understand that? Anyone is free to enjoy the music any way they like. If they want to remain ignorant they can. If they want to get their knickers in a twist, they can.

But some of those who wilfully do that seem to have a great resentment that others may get more from the music by knowing something about it.

And the informed historical approach does offer more. It in no way reduces the musical pleasure. It in no way inhibits the imagination. It enables the political dimension. So it offers at least two enhancements that ignorance does not.

I am curious though. Waht is the objection to the expression "from the singing of"? It seems a parallel to the common usage of "an "x" song" to mean a song recorded by, rather than written by "x".
