Also the first chord in "Hard Days Night" is just an F9 chord in C, like you can hear in a billion other places long before the Beatles. I know this is beside the point and is going to sound snobbish, but it's not like the Prometheus chord[1] of Scriabin or the "So What" chord[2] which Bill Evans came up with, or a bunch of other things which are genuinely interesting and novel from a harmonic point of view.

The Beatles may have been a major cultural phenomenon, but whatever impact they had it wasn't down to things like that chord. I find it pretty annoying when journalists tend to do this kind of thing to add a bit of colour.
