Billboard has published a list of the 21st century's top 25 producers, ranking producers by how many No. 1 hits they've landed on the Billboard Hot 100 since the turn of the millennium, and the results may surprise you.
The winner, however, is no surprise. Swedish superproducer Max Martin landed the top spot in Billboard's rankings, having absolutely dominated the charts since securing his first No. 1 with Britney Spears' ...Baby One More Time in 1999.
