Music recommendation playlists usually ignore non-music cultural context and harmonic key flow. When a listener or DJ wants a setlist that feels like a Wong Kar-wai film, a Haruki Murakami novel, and a Kyoto kissaten listening bar, tracks need both cross-domain cultural resonance and smooth harmonic transitions. SetlistForge combines Qloo-style cross-domain taste conditioning with a beam-search energy and Camelot wheel harmonic sequencer.

What it does

Cross-Domain Cultural Seed Conditioning: Select 1 to 4 seeds across 4 domains (Films & Directors, Books & Essays, Sonic Venues & Aesthetics, and Music Tracks) to compute an 8-dimensional taste centroid (tempo, valence, acousticness, cinematicTension, nostalgia, lyricalDensity, subculturalEdge, warmth) and inspect the explainability bridge showing why each track resonates with your non-music seeds.
Beam-Search Energy & Harmonic Sequencer: Sequences 6 to 12 tracks along a selectable 6-stage energy spline (Slow Burn Crescendo, Late-Night Noir Wave, Peak-Hour Festival Arc, Warm Acoustic Dawn, or custom faders) while jointly optimizing seed taste affinity, target energy MSE, and Camelot wheel harmonic transitions (0 step, ±1 fifth, or relative major/minor A<->B).
Web Audio API Harmonic Transition Synthesizer: Audition any adjacent track transition directly in the browser using dual-chord oscillator synthesis and lowpass filter envelopes.
Live Qloo Insights API Connector & Export Console: Connect a live Qloo API key (https://hackathon.api.qloo.com/v2/insights) and export playlists as .m3u8, .json, or Markdown liner notes.

How we built it

Built in zero-dependency vanilla JavaScript (engine.js, app.js) with an interactive SVG energy/harmonic transition curve, Web Audio API chord synthesizer, and 30 unit and DOM smoke tests via node:test.
