Pre-flight validation for every distributor.
Every distributor has its own rules - allowed genres, file format requirements, metadata field minimums, naming conventions, ISRC handling, lead-time windows. Most are documented across PDFs and partner portals; most labels learn them by getting a release rejected. Distributor Playbook is the rule set codified into Labelflow.
The rules, made operational.
Distributor-specific rule library
Every distributor's actual rules - genre allow-lists, metadata field minimums, naming conventions, ISRC handling, lead-time windows. Maintained centrally, updated as distributors update their rules.
Pre-flight validation
Before a release ships, it's checked against your distributor's actual rules. Anything that would trigger a rejection is flagged with the specific rule that's failing.
Specific error messages
Not "metadata invalid" - "track 4's genre tag isn't on this distributor's allow list" or "ISRC for track 2 conflicts with an earlier release". You know what to fix.
Auto-fix suggestions
Where the fix is obvious, Labelflow proposes it. Genre tag mismatch? Here are the closest accepted alternatives. Metadata field empty? Here's what to fill in.
The submit-and-wait-for-rejection loop.
Bundled in every plan. Proton at launch.
Distributor Playbook is core - bundled in every tier. Proton SoundSystem rules ship at launch; more distributors added throughout the year as the rule library expands. See pricing → See the roadmap →
Ship clean. Every time.
Beta is invite-only. The Distributor Playbook starts paying back on the first rejection it prevents - the days of release-cycle time you keep instead of lose.
