"So, how do you put together your charts, anyway?" Republic superstar Post Malone asks our own Jamie Mitchell during Posty Fest in Dallas. Jamie proceeded to explain that after inputting a series of data variables into a stochastic algorithm, he then calculates a median percentage based on sales, subscription, ad-supported and other consumption factors. "After that," he added, "I bury a potato under the full moon and wait for the mole people to appear in my dream." Seen before enjoying a delicious bowl of Posty Toasties are (l-r) manager Dre London, Republic's Matty B, Jamie and Post.
