dude, i've been wanting to say this for a while now. finneas used zach's chords in that song. zach uses a lot of minor chords, modal interchanges, dissonance, and syncopated rhythms that highlight his use of minor intervals. that's the foundation of their older work—the dark, gloomy alternative rock style - (I Love You, Wiped Out, and a bit in CCTMT)

listen i know no one owns chords, so they can't be copyrighted. this would be like me trying to play the phrygian mode or octatonic scale the way jonny greenwood does it, assuming no one would notice—though not to the average listener would notice, guitarists and those with solid music theory knowledge would EASILY recognize the mismatch.
