That's exactly what I did, and they changed the link and modified the discussion!

Notice, people below were talking about RapGenius specifically, their VC, and how much a license costs - yet that stopped once the editors modified the URL & headline.

All of that is fine and probably true but doesn't respond to the rule from the FAQ:

Please submit the original source. If a blog post reports on something they found on another site, submit the latter.

I'd suggest posting your additions to the comments here to stir the discussion.

I was excited to read your article because based on this comment I thought it would have in-depth analysis of the issue, but I found it to be a very shallow in terms of additional content. It has one paragraph with the licensing costs, which is useful information, and then the two sentence blurb on David Lowery, which didn't seem to be meaningfully connected to the issue at all (it actually is somewhat negative in my view, because it seems to imply a slight hint of perhaps ad hominem, but that was just my initial impression, and doesn't seem totally justified upon rereading). If you had multiple discussions with song publishers and research on this topic, it would definitely be valuable to share them.

With respect to disrespect, Hacker News exists for the benefit of its readers, and not necessarily for the benefit of the Internet's citizen-journalist army. Hacker News admins prefer "canonical" sources in most situations. That said, I wouldn't consider your post "blogspam."
