These all-time rankings are based on actual performance on the weekly Adult Pop Songs chart, from its launch in Billboard magazine dated March 16, 1996, through March 12, 2016. Titles are ranked based on an inverse point system, with weeks at No. 1 earning the greatest value and weeks at lower rungs earning the least. Due to changes in chart methodology over the years, eras are weighted differently to account for chart turnover rates over various periods. Artists are ranked based on the combined point totals, as outlined above, of all their Adult Pop Songs chart entries.
