The problem
Music apps optimize for popularity, not emotional state.
The solution
Users describe their mood in plain English and get hyper-specific playlists.
Who it's for
Gen Z listeners who want vibe-first discovery, not another top-50 chart.
Recommended stack

First-week milestone
A single text box that takes a mood, generates a 20-track YouTube playlist, and lets the user save it. Journaling comes later.
Distribution playbook
- TikTok screen-recordings of 'wild mood prompts' producing surprisingly good playlists.
- Share-a-vibe link with friends — every shared playlist drives a new signup.
- Seed r/Music, r/letstalkmusic, and niche genre subreddits with the most unhinged prompts.
Guardrails & risks
- YouTube quotas reset daily — cache mood→video mappings so you don't burn quota.
- Don't claim 'AI knows your mood' — frame it as 'AI translates your words into music', which is true.
- Spotify/Apple Music are upgrade paths, not v0. Both have real friction (OAuth review, $99/yr Apple Dev).
Validation signal
Day-2 retention is the only number that matters here — if people come back tomorrow with a new mood, you've got it.
Gen Z Appeal
Emotion-first discovery is highly addictive.
