Country pop music is often known for genres like rock, pop, and country combined.  It is a continuation of similar efforts that began in the late 1950s originally known as Nashville sound and later on Countrypolitan.  By the mid-1970s, many country artists were transitioning to the pop-country sound which led to some records charting high on mainstream top 40 as well as country "Billboard" charts.
