Country music was aided by the U.S. Federal Communications Commission's (FCC) Docket 80–90, which led to a significant expansion of FM radio in the 1980s by adding numerous higher-fidelity FM signals to rural and suburban areas. At this point, country music was mainly heard on rural AM radio stations; the expansion of FM was particularly helpful to country music, which migrated to FM from the AM band as AM became overcome by talk radio (the country music stations that stayed on AM developed the classic country format for the AM audience). At the same time, beautiful music stations already in rural areas began abandoning the format (leading to its effective demise) to adopt country music as well. This wider availability of country music led to producers seeking to polish their product for a wider audience. In 1990, Billboard, which had published a country music chart since the 1940s, changed the methodology it used to compile the chart: singles sales were removed from the methodology, and only airplay on country radio determined a song's place on the chart.
Sometimes it takes an ‘American Woman’ to break into the US charts, and that’s what Canadian powerhouse rock group, The Guess Who did in 1970, being the first Canadian group to have a US chart topper since 1954. Powered by the soulful vocals of Burton Cummings and Randy Bachman’s driving guitar and sardonic songwriter, the Winnipeg-based band found international success throughout the 60s and 70s, until disbanding when Bachman left the group and went on to form the hugely successful, Bachman-Turner Overdrive, with their hit single ‘You Ain’t Seen Nothing Yet’.
Emerging out of the great depression on near equal-footing to American popular music, Canadian popular music continued to enjoy considerable success at home and abroad in the preceding years. Among them Montreal's jazz virtuoso Oscar Peterson (1925–2007) who is considered to have been one of the greatest pianists of all time, releasing over 200 recordings and receiving several Grammy Awards during his lifetime. Also notable is Hank Snow (1914–1999), who signed with RCA Victor in 1936 and went on to become one of America's biggest and most innovative country music superstars of the 1940s and 1950s. Snow became a regular performer at the Grand Ole Opry on WSM in Nashville and released more than 45 LPs over his lifetime. Snow was one of the inaugural inductees to the Canadian Songwriters Hall of Fame started in 2003.
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. Many of the artists during the latter half of the 1980s drew on traditional honky-tonk, bluegrass, folk and western swing. Artists who typified this sound included Travis Tritt, Reba McEntire, George Strait, Keith Whitley, Alan Jackson, Ricky Skaggs, Patty Loveless, Kathy Mattea, Randy Travis, Dwight Yoakam, and The Judds. https://www.youtube.com/watch?v=GVVwOl9eZdA
