Isrc/iswc mapping, split-sheet verification, and eliminating black-box

Key Takeaways

  • Every unclaimed royalty sits in suspense for 24 to 36 months, then gets liquidated to major labels.

  • Your master rights and publishing rights are separate systems with separate identifiers and separate collection societies.

  • Split sheets must close at 100.00% before stems leave the studio, or you're building a royalty dispute.

  • Sync licensing requires 200% clearance: 100% master control and 100% publishing control, verified and documented.
