Of particular note, in 2012, "Billboard" restored recording sales to the chart formula but also added airplay from non-country stations, giving an inherent advantage to country pop crossover songs, at the same time maintaining the 1990 formula solely to measure country radio airplay. After the change, crossover songs have increasingly set the record for the longest run atop the country chart for longer and longer stretches; "Meant to Be" currently holds the record, 50 weeks and counting as of November 2018, more than double the pre-2012 record (Leroy Van Dyke's "Walk On By" was atop the chart for 19 weeks in 1963, during the 1958-1990 period of a unified sales, jukebox and airplay chart; three songs topped the various separate country charts for 21 weeks each between 1948 and 1955).
