Track Metadata in Velveteen
Updated June 12, 2026
Track metadata is the recording-level information Velveteen checks before a release can be submitted: title, display artist, genre fields, audio locale, language, P line, preview settings, AI declaration, explicit flag, and ISRC settings.
These fields describe the recording. They sit beside release metadata, not underneath it.
Submission-critical fields
Title and display artist
The track name and public artist string.
Genre fields
Track genre fields must be present where required and cannot duplicate each other.
Audio locale and language
Non-instrumental tracks need language. Instrumental tracks use ZXX.
P line
P year and P text are required at track level.
Preview
Preview start and preview length are required and must fit inside the track duration.
AI declaration
Velveteen requires an AI declaration before submission.
Single-track releases
If a release has exactly one track, Velveteen checks that the track genre fields match the release genre fields.
That keeps one-song releases consistent across both the package and the recording.
