Chimp said, "What is puzzling is why so many of the so-called country stations don't really sound country."
With respect, this may be the reason.......
Could it be that "sounding country" is NOT a positive, today as it may have been when the salesman got stuck in (the peaceful setting of) Mayberry for a few days, and Aunt Bea fixed him a few meals and Gomer had to fix his car?
These days, there is a "Sleep Cheap" with cable and HBO, and even a "Waffle House" near Mayberry. He could het his radiator fixed at the local "Pennzoil" or "Midas" place.
Maybe it's because Minnie Pearl and Grandpa Jones and Ferlin Husky are "grandma and grandpa's" country. "Ol Ern" is no longer with us, with a gaping hole where a tooth ought to be (see I Love Lucy).
Today's country fans have been to the big city more than an "annual trip." They've been down the interstate to the mall - so "the jot 'em down store" (listen to Lum & Abner) in Puff Bluff isn't enough and the TV station in Pixley (see And Griffith) is now a Fox affiliate that shows per-inquiry "bad girls" infomercials with censored "bits" just before sign off.
Where I live (in the midwest) I know an adult guy (the only one with this habit) who wears western apparel and cowboy boots. Some mean people say he looks like "Roy Rogers" and they laugh at him behind his back
To me, it is very sad that when he leaves, people ridicule him just because of his choice of clothes. I am among his few friends.
For some people "sounding country" may denote a stereotype of "barefoot and poor," "hillbilly," "uneducated," "moon pies and Dr. Pepper," "aw shucks"- even poor use of English..while "contemporary hits" can denote, "modern," "with it," "more affluent" "upward mobile", "money to spend" - whether these impressions are true or not.
Thirty (!!) years ago, WMAQ, Chicago was a hugely successful "country" station that offered country (and crossover) music with a fast moving style, BIG contests, and a "top 40 sound" presentation.
VERY clever to not alienate the (more sophisticated) Chicago audience while still offering "country music." Chimp, as I have tried to explain before, the reason is MONEY- nothing more.
Maybe that is why. Maybe not.
