Billboard names Macklemore & Ryan Lewis' 'Thrift Shop' the hottest rap song ever

In addition to Billboard's list of the top 50 Hot Rap Songs artists, the artists with the most No. 1s and the artists with the most top 10s, the magazine compiled a list of the top 100 chart-performing rap songs ever to commemorate the 25th anniversary of their Hot Rap Songs chart. You won't believe who took home the No. 1 spot.

Billboard named Macklemore & Ryan Lewis' "Thrift Shop" the hottest rap song ever.

Billboard says they measured each track's positions on the coveted chart and used a point system to tally every rap song's charting history over the last quarter-century.

Here's how Billboard explained it:

"The 25th Anniversary Hot Rap Songs ranking is based on actual performance on the weekly Hot Rap Songs chart, since the chart's inception in the March 11, 1989, issue. Rankings are based on an inverse point system, with weeks at No. 1 having the greatest value and weeks at lower positions proportionately less. Due to various changes in chart rules, chart length and methodology throughout the years, songs had varying reigns at No. 1 and on the chart. To ensure equitable representation of the biggest hits from all 25 years, certain time frames were weighted to account for the difference in turnover rates from those periods."
