Back when there was this thing called "new country" Wenatchee The Hatchet heard about it sounded like old rockabilly that was reheated in a microwave, much like grunge was the same sort of thing with punk. WtH has no problem with country in principle. Johnny Cash, Hank Williams Sr. and Merle Haggard may be a bit more pop than country, maybe, but basically country written and performed by people born before 1960, that's okay.
New country, no. New new country of the sort that gets targeted at the link above ... that's basically just pop.
Most of the contrasts across styles in contemporary Western popular styles that gets anywhere near Billboard seem to be more a matter of preferences in timbre and the pace of harmonic rhythm. If you lean toward long and tedious rambling on over a single chord then you're more of a Zeppelin fan, natch.
But the chords in the six songs mashed up in the link. The chord changes sounded threadworn and lame ... like the chords were used in some chorus in some song that's not even country but more like ...
"chords for heroes"
If the six mashed up songs are the sound of new country then why don't people just keep on listening to Boston?
The first couple of Boston albums may have been played to death but the songs that cement the clichés are the ones that get to own `em better.
