I don't mean to pick too much on one comment and certainly not personally on the GP! This is just a common problem on the internet. What we want on HN is the kind of comments that enrich curious conversation. If you really don't think there is anything curiosity-gratifying in an article, that's what flags are for.
While I do agree, in general a lot of novel ideas get dismissed out-of-hand, a conversation about to what extent an idea engages with the existing community/literature around that idea is valuable. For example, if I saw a paper posted here that claimed it solved P!=NP, my first question would be as to how much it addressed the existing work, as mathematical ideas tend to attract cranks.
this article makes grand claims about how the brain works that are not backed up by any experiment or reference; it's reducing an extremely complex phenomenon - music and subjective experience of music - to a simple cognitive processing and meaning-making framework
The difference is here you say something a bit more specific about the content and topic of the article, whereas the GP comment didn't. Also, the style of what you wrote here is more conversational. The GP comment felt more like a pedantic putdown to me, although admittedly that is more of an interpretation.
