It is all a matter of personal taste, nothing more-nothing less.I really need for you to define your interpretation of "purist" in more specific terms. As I am; at a loss, after reading most of the other postings I believe just about every individual involved could, to some degree, be categorised as a purist.I love music - be it classical to current chart music (in small doses) and lots in between and I have been told that I am a purist because of my devotion to The Beatles etc.But as I say; I love and buy lots of varied music. It seems to me to come from a desire to belong to a social group, or used by others to exclude from their clique, or simply to label individuals as a means to make others feel superior or more comfortable within social groupings. There is no shame in being called a purist it signifies a commitment to the cause beyond and above the call of duty and wearing your badge with pride in a world of 5 minute wonders and fickle fashions you stay true and unwavering.
Keep The Faith.
