Y Combinator names music discovery as a classic 'tarpit': lots of founders try it, users love the demo and never come back. You can build on Spotify's data, but in Nov 2024 Spotify restricted its recommendation and audio-analysis endpoints for new apps — the exact data a discovery tool needs. Possible, but go in with eyes open.
The way in: Recommendation/analysis tools on Spotify's API — but the endpoints you'd need are now restricted for new apps.
Moat: the licensed catalog is the product · platform risk: high · why: YC lists music discovery as a classic tarpit · Spotify restricted recommendations/audio-features for new apps Nov 2024
