I watched a friend pour months into an album that blended folk and industrial. Bookers told him, "We don't know where to put you." Labels wouldn't touch it. The music was solid, but it didn't slot into a category. That's not a shared vocabulary — that's a gate.
You're right that constraints can spark creativity. The study you mentioned proves that. But genre labels aren't the same as creative constraints. The constraint is the harmonic framework or the sampling limits you choose. The label is the expectation other people impose. Once you call something "jazz," you've already set an audience's ear to compare it to Coltrane. That's an external cage, not an internal one.
Kendrick's To Pimp a Butterfly worked because he didn't stay in one genre. He used jazz, funk, and rap as foundations, not as a definition. So why keep the labels at all? Let music be
