Since we started Planet Money Records and released the 47-year-old song "Inflation," the song has taken off. It recently hit 1 million streams on Spotify. And we now have a full line of merch — including a limited edition vinyl record; a colorful, neon hoodie; and 70s-inspired stickers — n.pr/shopplanetmoney. After starting a label and negotiating our first record deal, we're taking the Inflation song out into the world to figure out the hidden economics of the music business. Things get complicated when we try to turn the song into a viral hit. Just sounding good isn't enough and turning a profit in the music business means being creative, patient and knowing the right people.This is part three of the Planet Money Records series. Here's part one and part two. Listen to "Inflation" on Apple Music, Spotify, YouTube Music, Tidal, Amazon Music & Pandora. Listen to our remix, "Inflation [136bpm]," on Spotify, YouTube Music & Amazon Music. "Inflation" is on TikTok. (And — if you're inspired — add your own!) This episode was reported by Erika Beras and Sarah Gonzalez, produced by Emma Peaslee and James Sneed, edited by Jess Jiang and Sally Helm, engineered by Brian Jarboe, and fact-checked by Sierra Juarez. Music: "Inflation," "Superfly Fever," "Nola Strut" and "Inflation [136bpm]."
