Tarpit Music streaming is owned by the record labels, not the app — you can't license the catalog.

The product here is the licensed music, not the software. Spotify and Apple Music pay the major labels huge guaranteed advances (and gave them equity) to carry their catalogs, and three labels control 70%+ of recorded music. A better player with no catalog is worthless, and a solo dev can't license the world's music — even well-funded Rdio died trying.

Moat: the licensed catalog is the product · why: Spotify pays ~2/3 of revenue to rights holders · 3 major labels control 70%+ of recorded music · labels took equity in Spotify for catalog access · Rdio shut down despite VC funding
