Imagine a commuter typing "rainy night, slow jazz, female voice" into an app and getting a fresh song every commute, tuned to their taste. No artist, no label, no royalties. That's not a gimmick; it's scale. Most music isn't consumed as sacred art, it's background, mood, workout fuel. AI will eat that market first because it's cheap, infinite, and personalized. Human artists won't vanish, but they'll be pushed toward live shows and niche prestige. That's replacement in the way that matters: who makes the music most people actually play.
