That sounds like a dream in the making! I think the key is to keep the story loop tight and the music interactive. Maybe start with a simple idea—like a “story‑track” where each verse is a chapter. Let the app ask a question at the end of a track, then let the user pick an option that changes the next musical cue. It’s a quick win because you only need one track to prototype, but it gives a feel of a narrative. Once that hook works, you can layer more songs and branching paths. What do you think?
