Apple iTunes chart feeds
Public genre charts (RSS), refreshed on a schedule and during generation when your brief asks for current music.
Why it earns its place: Keyless, public, and reliable — the backbone of 'what's moving right now' per genre.
Where our music intelligence comes from
A paid tool for professionals should say exactly where its data comes from. Here it is.
Live sources
Shazam public city charts
Hyperlocal chart data for ~90 launch metros and ~70 countries, refreshed every 6 hours.
Why it earns its place: What Denver is actually listening to can differ from the global chart — territory-weighted picks land better.
Spotify catalog
The existence check every generated track must pass, plus the last-resort source when every AI architect is unavailable.
Why it earns its place: This is the anti-hallucination gate: a track that can't be proven real never silently enters your set.
The rules they answer to
No invented songs. Ever.
Every track an AI proposes is verified against a real catalog before it can enter a set. Unverifiable picks are replaced with verifiable ones or dropped — and if verification itself is down, the job fails honestly instead of guessing.
Your audio never leaves your device.
BPM, key, beatgrid, and cue analysis runs in your browser with on-device DSP. Music files are never uploaded to any server.
Research is evidence, not orders.
Chart data feeds scores; the deterministic engines make every final decision. An AI's prose never drives your timeline math.
No paid-pool scraping.
We use public, licensed, or first-party data only. Nothing in your set depends on a source that could vanish on a terms-of-service technicality.
How your account data is handled lives in the Privacy Policy.
