I'm amused by the fact that this person doesn't seem to know that chords per se - and the analysis of them - is practically useless because they can and actually do vary from version to version of the same song. The thing that matters is how the chords are related (modes and progressions).

I don't know -- I still thought it was interesting. The author could have spent all kinds of time trying to figure out if certain chords were functioning as substitute dominants and all of that, but then the article would have been so musically technical so as not to appeal to anyone who doesn't have a fairly high-level music theory background.

Knowledge of rudimentary music theory makes this link upsetting in what it's missing. It looks at data in the wrong way.

I hope that other articles on HN don't fall apart like this if you know a little about the subject.

Exact same thoughts here. Statistics analysis is completely irrelevant when it comes to music (and any form of art of course).

That said, the whole attempt is impressive (from an engineer's perspective)
