Republic star and streaming sensation Post Malone brandishes his Pandora "Billionaire" plaque, presented to him backstage at Fallon and representing more than 1 billion streams on the platform, where he remains the #3 global artist overall. It's worth noting that Post earned his billion on his own, and not via inheritance, loans, tax dodges or Russian money laundering. You can check out Pandora's A-Z Post faves playlist here.
