Chart Legend
Singles
Country Airplay (formerly Hot Country Singles) - Chart position is ranked by number of total audience impressions,
not actual spins. It was changed to this format in January 2005. The country singles chart included 75 songs until
January 6, 2001 when it was reduced to 60 songs. Songs are removed from this chart if they have been on the chart for more
than 20 weeks and rank below 15 in detections (spins) or audience, provided they are not gaining enough audience points
to bullet.
Hot Country Songs - Radio airplay plus sales data plus streaming data
