I’d go through all of the chord progressions and make sure they actually match what is being played. There are quite a few errors. Happens to everyone.
Also, you and everyone else should remember that while the band is mostly playing power chords and omitting the fifths, what Cobain sings is part of the chord as it’s heard. This means that, for example, a lot of songs do sound major, Smells like teen spirit is probably in F minor.
I find determining key in popular music to be tricky. Most progressions consist of something like 4 chords, and there isn’t the teleology you see in something like Tin Pan Alley or Chopin to give the sense of where one is to arrive. Even the Axis of Awesome progression can be heard a major or minor depending on how you end the song.
Although I wonder if mathematically it’s the same thing …
Essentially it's a glorified pseudo random generator, like many of the algorithmic composition ideas of the time.
It definitely is not a glorified PRNG. The idea is that you can create patterns that have both variety and repetition with them. I don't like the results, generally, but they are not random.
It’s really cool to use quantum computers to compose music, but I’d love to see them used for things other than control of “frequency modulation (FM), additive synthesis, and granular synthesis.”
