The "C&W" used in the titles of the charts was an abbreviation for "country and western", a term which Billboard had adopted for the genre in 1949, replacing the earlier "folk music".
[2] At the start of 1957, the number-one position on all three charts was held by "Singing the Blues" by Marty Robbins, who achieved a second number one in June with "A White Sport Coat (And A Pink Carnation)".
Elvis Presley was the only act with three country number ones during the year; he reached the peak position on the juke box chart in May with "All Shook Up" and later in the year topped the best sellers chart with the double-sided entries "Teddy Bear" / "Loving You" and "Jailhouse Rock" / "Treat Me Nice".
Sonny James achieved his first country number one in 1957 with "Young Love", which also topped Billboard's pop airplay chart.
