For closed testing and also a closed beta to understand if the product gets traction, v0.3 is going to work and does exactly what we want. For free usage or ad based revenue, v0.3 also works. But if we want to monetize the product by selling licenses, we need to self host the audio and work w/o Spotify. A full Spotify integration is only possible once we reach 250k MAU, so out of the picture for MVP.
