Nothing against professional marketers and publicists, but there's no better hype than having Taylor Swift's endorsement.
Taylor went on social media to praise Post Malone's new album, "F-1 Trillion", and said, "I was lucky enough to hear this amazing music, when Austin played it for me. It's incredible how versatile his artistry is. And [he's] just the most down to earth guy alive."
If you didn't know, his real name is Austin Post, and he's featured on Taylor's last album, "The Tortured Poets Department". He co-wrote "Fortnight".
