The ranking is based on actual performance on the weekly Billboard Hot 100 chart. Songs are ranked based on an inverse point system, with weeks at No. 1 earning the greatest value and weeks at No. 100 earning the least. To ensure equitable representation of the biggest hits from each era, certain time frames were weighted to account for the difference between turnover rates from those years.
