Data Sources & Attribution

Last updated: May 11, 2026

SonoVault is a metadata aggregator. We don't produce the underlying catalog ourselves — we collect, normalize, and cross-reference factual track information (titles, artists, ISRCs, release dates, genre, identifiers) from a handful of upstream sources, and serve it through a single REST API. This page documents who those sources are, how the data is accessed, and how each one is attributed.

Every upstream source is accessed under its own terms — public data dumps, official developer APIs, or both. SonoVault does not scrape, bypass auth, or redistribute anything we're not permitted to.

Streaming and storefront platforms

For Spotify, Apple Music, Tidal, and Beatport, SonoVault stores only the platform-specific track IDfor each recording — the identifier needed to resolve a track to its equivalent on that platform. We do not store or redistribute catalog metadata, audio, audio previews, artwork, or any other content from these platforms. Track IDs are obtained through each platform's official developer or partner API under their respective developer terms.

Audio previews or full audio. No audio content of any kind is served by the API.
Proprietary lyrics, reviews, or editorial content.

How records are reconciled

ISRC is the primary key when available — two records with the same ISRC are treated as the same recording. Where ISRC is missing, normalized artist and title matching with confidence scoring links the same recording across platforms. Field-level conflicts between sources are resolved using a confidence-weighted preference per field, so the most reliable available value wins.

Errors, removals, and rights inquiries

If you believe metadata served by SonoVault is incorrect, infringes a right you hold, or should be removed, contact support@sonovault.nowwith the relevant track or release identifier and we'll act on it. Trademark and rights holders mentioned on this page can request changes to attribution wording at the same address.

Changes to this page

We update this page when an upstream source is added, removed, or changes its terms in a way that affects what we store or how we attribute it. The “Last updated” date at the top reflects the most recent revision.
