Is it music? Sure - I've said before that if one person finds particular sounds to be music, I'm not one to disagree.
Is it sacred? Not to me, but hardly anything is sacred to me beyond individuality and family.
Is it boring? Well, it never sounds exactly the same in a "live" setting.
Is it tied in to one or more non-western religions? I don't care.
Is disparaging the piece disrespectful? No, I understand why many folks find it to be nothing.
Is finding value in the piece unreasonable? No.
