But this phenomenon is real among music purists. There is not irony in the real act of exclusively guarding the sharing of music that is known to put the listener into the state of mind of musical enjoyment unlike anything one has heard before. I would argue that is the a main point of music, and replaying the same sounds at every concert can work but what if the audience had no idea what to really expect? Their minds cannot predict and hence the stimulus hits different. But again, some minds may not want that.
