The September 11 attacks of 2001 and the economic recession helped move country music back into the spotlight. Many country artists, such as Alan Jackson with his ballad on terrorist attacks, "Where Were You (When the World Stopped Turning)", wrote songs that celebrated the military, highlighted the gospel, and emphasized home and family values over wealth. Alt-Country singer Ryan Adams song "New York, New York" pays tribute to New York City, and its popular music video (which was shot 4 days before the attacks) shows Adams playing in front of the Manhattan skyline, Along with several shots of the city. In contrast, more rock-oriented country singers took more direct aim at the attacks' perpetrators; Toby Keith's "The Angry American (Courtesy of the Red, White and Blue)" threatened to "a boot in" the posterior of the enemy, while Charlie Daniels's "This Ain't No Rag, It's a Flag" promised to "hunt" the perpetrators "down like a mad dog hound." These songs gained such recognition that it put country music back into popular culture. The influence of rock music in country has become more overt during the late 2000s and early 2010s as artists like Eric Church, Jason Aldean, and Brantley Gilbert have had success; Aaron Lewis, former frontman for the rock group Staind, had a moderately successful entry into country music in 2011 and 2012. Also rising in the late 2000s and early 2010s was the insertion of rap and spoken-word elements into country songs; artists such as Cowboy Troy and Colt Ford have focused almost exclusively on country rap (also known as hick hop) while other, more mainstream artists (such as Big & Rich and Jason Aldean) have used it on occasion.
Rock and roll has usually been seen as a combination of rhythm and blues and country music, a fusion particularly evident in 1950s rockabilly. There has also been cross-pollination throughout the history of both genres; however, the term “country-rock” is used generally to refer to the wave of rock musicians of the late 1960s and early 1970s who began recording rock songs with country themes, vocal styles, and additional instrumentation, most characteristically pedal steel guitars. John Einarson states, that "[f]rom a variety of perspectives and motivations, these musicians either played rock & roll attitude, or added a country feel to rock, or folk, or bluegrass, there was no formula".
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
