Track 11 Goodbye, and thank you! This story the story of boy and girl bands turned out to be richer and more surprising than I expected. If you've made it this far through the soul origins of the Temptations, the golden age of Orlando, the modern hybrid of BTS and One Direction, the spillover tables, the sixteen band pro les, the great absentees and the twenty songs of the playlist then you already know that this project is not a ranking. It's not a list of "bests." It's an attempt to understand what happens when one billion people press play on the same song. Thank you for reading. Genuinely. Every volume of 10 will start from a precise idea the idea of numbers that tell stories. And this story, the one about boy and girl bands, turned out to be richer and more surprising than I expected. 162
