1,000 tracks, 100 mixes, 82 mood tags: we built a free focus-music library and kept the receipts

Focus music is a solved problem if you like handing your attention to an algorithm that also sells ads. We wanted the opposite: a library where every track exists because someone wrote a recipe for it, and the recipe is kept. The Dracon music library is 1,000 tracks organized into 100 curated collections we call cooks — and because the whole thing is a data file, we can tell you exactly what's in it.

The cooks have names like Late Night Lo-Fi, Deep Focus Pulse, Cloud Garden, Neon Drive, and Iron Cathedral — each one a 10-track run at a specific headspace. About half the library is fully instrumental, which is the half most people leave on while working.

The receipts: every track keeps its recipe

Each of the 1,000 tracks was generated with its full parameters stored: the prompt, genre, mood tags, instrument list, BPM, key, and structure. A real example from the library — 'Lo-fi hip hop instrumental, mellow late-night study vibe, dusty vinyl samples, warm rhodes piano chords, muted thumb bass, soft brushed drum loops with vinyl crackle' at 75 BPM in F minor. That's not marketing copy; it's the actual generation record. It means the library is auditable and reproducible — when we say 'dark ambient for deep work', we can show you the 200 recipes behind that claim.

How to use it

Open the player, pick a cook that matches the headspace you need — Deep Focus Pulse for flow work, Late Night Lo-Fi for the evening shift, Iron Cathedral when the code review needs gravitas — and press play. No account, no ads, no algorithm deciding you've had enough focus for one day. The library view lets you browse all 100 cooks at once — or jump straight into Late Night Lo-Fi to hear what the recipes sound like. It's free because it's ours: the marginal cost of you listening to a track we already generated is zero, and charging for zero felt silly.
