I don’t know if this came up as I have not read the whole thread but an important factor to me is that if someone defines what they have created as music then I would never tell them it is not. I might not like what I hear (or however it is presented) but I don’t think it would give me the right to not call it music. That would feel like censorship to me. It might be my limited understanding that hinders me from seeing its beauty or it might in fact just be rubbish. I’ll mostly never know so I try not to judge what I hear/experience.
I think there is this important link between time, space and memory that makes music so compelling to me. And by space I don’t only mean the architectural room which, of course, has its impact, but also the sociology of the space.
I also find it very interesting that the non-lieu as defined by Marc Augé (from Wikipedia: anthropological spaces of transience where the human beings remain anonymous and that do not hold enough significance to be regarded as " places") has such a specific sound to it.
