Doubly Blackbox Checker is a free tool that helps songwriters discover unclaimed mechanical royalties at The MLC. By pasting a Spotify link or searching by name, you can see which of your recordings are missing, unmatched, or have unclaimed shares, and estimate the money stuck in the 'black box.' It leverages The MLC's public data to provide a clear status for each recording, from 'Looks good' to 'Missing work,' and explains how to fix issues. With a user-friendly interface and detailed explanations, it empowers artists to protect their earnings before the 2027 market-share distribution.
This tool shows you how much of your catalog is stuck in the black box, so you can claim what's yours before it's redistributed.
