Fourth generation (1970s–1980s) music included outlaw country with roots in the Bakersfield sound, and country pop with roots in the countrypolitan, folk music and soft rock. Between 1972 and 1975 singer/guitarist John Denver released a series of hugely successful songs blending country and folk-rock musical styles. During the early 1980s country artists continued to see their records perform well on the pop charts. In 1980 a style of "neocountry disco music" was popularized. During the mid-1980s a group of new artists began to emerge who rejected the more polished country-pop sound that had been prominent on radio and the charts in favor of more traditional "back-to-basics" production; this neotraditional movement would dominate country music through the late 1980s and was typified by the likes of George Strait. Attempts to combine punk and country were pioneered by Jason and the Scorchers, and in the 1980s Southern Californian cowpunk scene with bands like the Long Ryders and Mojo Nixon.
During the mid-1970s, Dolly Parton, a successful mainstream country artist since the late 1960s, mounted a high-profile campaign to cross over to pop music, culminating in her 1977 hit "Here You Come Again", which topped the U.S. country singles chart, and also reached No. 3 on the pop singles charts. Parton's male counterpart, Kenny Rogers, came from the opposite direction, aiming his music at the country charts, after a successful career in pop, rock and folk music with The First Edition, achieving success the same year with "Lucille", which topped the country charts and reached No. 5 on the U.S. pop singles charts, as well as reaching Number 1 on the British all-genre chart. Parton and Rogers would both continue to have success on both country and pop charts simultaneously, well into the 1980s. Artists like Crystal Gayle, Ronnie Milsap and Barbara Mandrell would also find success on the pop charts with their records. In 1975, author Paul Hemphill stated in the Saturday Evening Post, "Country music isn't really country anymore; it is a hybrid of nearly every form of popular music in America."
Folk songs sung in Australia between the 1780s and 1920s, based around such themes as the struggle against government tyranny, or the lives of bushrangers, swagmen, drovers, stockmen and shearers, continue to influence the genre. This strain of Australian country, with lyrics focusing on Australian subjects, is generally known as "bush music" or "bush band music". "Waltzing Matilda", often regarded as Australia's unofficial national anthem, is a quintessential Australian country song, influenced more by British and Irish folk ballads than by American country and western music. The lyrics were composed by the poet Banjo Paterson in 1895. Other popular songs from this tradition include "The Wild Colonial Boy", "Click Go the Shears", "The Queensland Drover" and "The Dying Stockman". Later themes which endure to the present include the experiences of war, of droughts and flooding rains, of Aboriginality and of the railways and trucking routes which link Australia's vast distances. https://www.youtube.com/watch?v=Uj5JQNLFSgA
