WBUX in Doylestown had country shows since the 1950's, and went all country in early 1967, months before WRCP. They were a daytimer and only covered the northern suburbs, but as a kid who liked country it was the only country station I could get other than WWVA at night. Also, about 1966 or so WIBF in Jenkintown started playing country weekday evenings with Doug Henson, the first FM country show here. So there was country for country fans, but hard to build a general audience around block programming.

And the FM signed off at midnight. They really didn't get the stereo right until about 1974, it was on & off for several years as the engineers experimented with it.

WUSL was "Continuous Country 99" and the jocks basically back-announced the songs and read the weather, pretty much sounded like easy listening radio, no energy or personality although some familiar names were there like Juan Varlita and Pat Winters.

A matter of personal taste & opinion, there were some good songs then & now, lots of crossover material then, too - Glen Campbell, John Denver, Anne Murray, Olivia Newton-John, Kenny Rogers, Dolly Parton, etc. Country seems to come in cycles, but always has a steady, loyal following.
