Background
DDEX ERN (Electronic リリース Notification) is the XML-based standard that music 配信 platforms use to communicate release data, audio files、および rights information to DSPs. Spotify formally moved to ERN 4.3 as its preferred ingestion format in Q4 2025, with a deprecation schedule for older ERN 3.x feeds running 経由 mid-2026.
ToneGrid's Spotify delivery pipeline has 今 been fully migrated to ERN 4.3. すべて 新着 releases delivered 経由 ToneGrid to Spotify go out in ERN 4.3 format as of today. Existing catalog is being re-delivered on a rolling basis over the next 30 days.
What ERN 4.3 Changes
ERN 4.3 is ではない a cosmetic upgrade. The specification introduced several substantive changes that affect how releases are described, delivered、および processed at the DSP level.
AI コンテンツ Disclosure Fields
ERN 4.3 includes mandatory fields for disclosing AI-generated or AI-assisted content — both at the sound recording および composition level. ToneGrid's ingestion layer 今 requires rights holders および distributors to declare AI content status at upload、および this data is passed 経由 to Spotify in the correct ERN 4.3 fields. Inaccurate disclosure is grounds for takedown under Spotify's updated content policies.
Enhanced Spatial オーディオ メタデータ
ERN 4.3 adds structured metadata fields for Dolby Atmos および Sony 360 現実 オーディオ deliveries, replacing the informal handling used in earlier spec versions. ToneGrid clients delivering spatial audio formats will 参照 improved processing times および fewer manual interventions at the Spotify side.
Improved Rights Expression
The rights expression layer in ERN 4.3 supports more granular territory-by-territory rights declarations, better adjacent rights holder identification (including producers および session musicians with registered shares)、および cleaner handoff for releases involving multiple rights holders across jurisdictions.
Transaction-Level Acknowledgments
ERN 4.3 delivery pairs with updated ACK (acknowledgment) messaging from Spotify. ToneGrid's delivery tracking 今 surfaces these ERN 4.3-level acknowledgments in real time — meaning distributors および labels can 参照 precisely where in Spotify's ingestion pipeline a release sits.
Rollout プラン
| Phase | Scope | Timeline |
|---|---|---|
| Phase 1 — 新着 releases | すべて 新着 deliveries to Spotify | 公開中 today |
| Phase 2 — アクティブ catalog | リリース from the last 12か月 | 次へ 14 days |
| Phase 3 — Full back catalog | すべて historical releases | Day 15–30 |
No action is required from ToneGrid clients. The upgrade is 対応済み entirely at the platform level.
その他 DSPs
Following the Spotify migration, ToneGrid will be upgrading Amazon Music, TIDAL、および Apple Music delivery feeds to ERN 4.3 over Q2 2026. Boomplay, Anghami、および JioSaavn use derivative DDEX profiles および will be updated according to their individual specification timelines.
The full DDEX ERN 4.3 upgrade across すべて active DSP接続 is expected to be complete by end of Q2 2026.
