Billboard's Top 10 Irish Artists ranking is based on actual performance on the weekly Billboard Hot 100 chart, dating to the chart’s Aug. 4, 1958, inception. The ranking is based on an inverse point system, with weeks at No. 1 having the greatest value and weeks at No. 100 proportionately less. Due to various changes in chart rules and methodology through the years, songs have had reigns at No. 1 and on the chart of varying average lengths. To ensure equitable representation of the biggest hits from all years, certain time frames were weighted to account for the differences in song turnover rates.
