We got our hands on the long-lost "Inflation" song, and now it's time to put it out into the world. So, we started a record label, and we're diving into the music business to try and make a hit. This is part two of the Planet Money Records series. Here's part one and part three. Update: We now have merch! We released a line of Inflation song gear — including a limited edition vinyl record; a colorful, neon hoodie; and 70s-inspired stickers. You can find it here: n.pr/shopplanetmoney. Listen to "Inflation" on Apple Music, Spotify, YouTube Music, Tidal, Amazon Music & Pandora.
