FAQ
How does Subterranea discover new music?
Subterranea uses AI to analyze bands you already enjoy and surfaces artists that are similar but less known. You can choose how deep into obscurity you want to dig, from well-known names to demos and tiny labels.
What are the different digging depths in Subterranea?
Subterranea offers four digging depths: Surface for canonical names, Underground for recognized but not household names, Deep for cult bands, and Bedrock for demos and buried gems.
Can I track the music I discover in Subterranea?
Yes, Subterranea allows you to track every find. You can mark bands as to-listen, listened, or favorite, and hide bands you already know to prevent them from resurfacing.
Is Subterranea private and secure?
Subterranea is designed for privacy with no account or login required, and no tracking. Your saved music library stays on your phone. Band queries are sent to Groq's AI for recommendations.
