DY: I didn’t quite deny that premise. However, we are intellectual beings and it’s not up to us to tell other people what Muttar things they are and aren’t allowed to be inspired by. If someone would scientifically prove (or at least give very strong, if not absolute, proof) that a certain type of music was guaranteed to only induce certain responses that are not all holy then of course it would be Assur. My point is that just because a certain type of music brings up not nice responses in you (you referring to whoever wants to Assur it, not you personally) doesn’t mean it does that for everyone.
As to your comment about refined music and Kedushah, once again “refined” is a subjective term. Classical music is the most refined music out there to most. Does it contain Kedushah? Maybe some would say that it does. I don’t know. But my whole point is that what people find inspiring is all subjective and no individual has the right or the ability to define or dictate inspiration.
