According to Lindsey Starnes, the term country music gained popularity in the 1940s in preference to the earlier term hillbilly music; it came to encompass Western music, which evolved parallel to hillbilly music from similar roots, in the mid-20th century. In 2009 in the United States, country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute.
1958 saw its first Canadian rock and roll teen idol Paul Anka, who went to New York City where he auditioned for ABC with the song "Diana". This song brought Anka instant stardom as it reached number one on the US Billboard charts. "Diana" has gone on to be one of the best selling 45s in music history. US-born rockabilly pioneer Ronnie Hawkins moved to Canada in 1958, where he became a key player in the Canadian blues and rock scene. The 4th of October was declared "Ronnie Hawkins Day" by the city of Toronto when Hawkins was inducted into Canada's Walk of Fame. He was also inducted into the Canadian Music Industry Hall of Fame and his pioneering contribution to rockabilly has been recognized with induction into the Rockabilly Hall of Fame. https://www.youtube.com/watch?v=gtKVuwDQUl0
