The Mechanical Licensing Collective, or MLC, is now trumpeting cumulative payouts of more than $1 billion to songwriters, publishers, and other compositional IP owners since its formal inception in 2020.

MLC chief executive Kris Ahrend has declined multiple requests by Digital Music News to clarify the specific black box amounts held by the organization.
