8 months. One beautiful analysis tool nobody needed. One overnight commoditization by big AI. And the pivot that turned it into something artists actually use: a song in, finished content out.
A song-analysis engine, stage by stage — tempo, key, structure, hooks, lyrics, instruments. Test material: our own songs. If the models couldn't explain why our best track was our best track, they weren't done.
You can't validate a Virality Score with vibes. So we built a fully legal dataset of song metadata and real streaming outcomes — hundreds of thousands of tracks over months — to check every scoring idea against what actually happened in the market.
The website ships. An early-access waitlist opens. First artists sign up before the product even exists — the promise alone (know what's viral about your song before you release it) was enough to get people in the door.
Upload → full analysis in about a minute. Virality Score, best moments, song DNA, lyric scoring. We tested relentlessly, shipped fixes daily, and onboarded our early-access artists.
Barely any user feedback. The funnel wasn't good enough — people looked at a beautiful analysis, said "cool", and left. And the market moved under us: general-purpose AI like Google's Gemini made "tell me about my song" a free chatbot prompt. Pure analysis was commoditized overnight. A score alone doesn't post itself.
We stopped selling the analysis and started selling what it enables. Now one upload returns 7 ready-to-post reels cut to your strongest seconds — beat-synced, word-accurate lyrics — plus captions and a 2-week posting plan. The analysis is still there. It's just the engine now, not the product.
Every posted reel you track teaches the system which angles work for which sound. That's the road ahead: analyze a song and know — from real outcomes — what kind of video works for music like yours. Good content in seconds, for artists without a budget, no prompting skills required.
Most musicians can't afford an editor, don't want to learn GenAI video tools, and shouldn't need prompting skills to promote a song. The tools exist — they just cost €100/month and a weekend of tutorials per release.
Songbrain's job is simple: good content in seconds, from nothing but your song.The analysis pipeline we spent 8 months building didn't die — it became the engine that knows exactly where your song is strongest and cuts the videos there. And every reel you post and track teaches it what kind of content works for music like yours.
