The Music Modernization Act built the pipe royalties still use

The tool moment

On 11 October 2018 the Orrin G. Hatch-Bob Goodlatte Music Modernization Act became Public Law No. 115-264. A songwriter routing a track through a streaming service does not usually think about mechanical licensing plumbing, but the Act rebuilt it. Title I created a blanket license for digital download and streaming services and directed a new Mechanical Licensing Collective, or MLC, to collect and pay out the resulting mechanical royalties; Title II brought pre-1972 recordings partly into federal copyright, with remedies for unauthorized use; Title III let producers, mixers and engineers receive royalties through SoundExchange by filing a letter of direction. None of this addresses whether part of a recording was AI-generated. It addresses whether, once a work is written and released, the money finds its way back to the people credited on it.

What the documents show

The Copyright Office's own implementation page describes the three titles and states that, as of 1 January 2021, songwriters and publishers must register their works with the MLC to collect royalties on covered digital uses. Congress.gov's record confirms the bill's enactment date and its formal short title. Neither document says anything about artificial intelligence; the Act predates the current AI-and-music policy debate by five years, and nothing in either source should be read as settling how an AI-assisted composition's authorship is determined. What the Act settles is narrower and more mechanical: who administers the blanket license, who registers to be paid, and how a producer's royalty share reaches SoundExchange.

What stays with the musician

Registering with the MLC does not establish who wrote a song, and it does not resolve whether an AI-assisted contribution can be claimed as authorship at all, a separate question the Copyright Office answers through its own registration guidance. A musician still has to identify co-writers accurately, document any producer or engineer entitled to a SoundExchange letter of direction, and keep the metadata that ties a recording to its registered work current. The Act moves money once those facts are settled; it does not settle them.

Judge it by listening

There is no listening test for a licensing statute. The practical check, editorially, is administrative rather than acoustic: does a release's metadata match an active MLC registration, and does every credited contributor who should file a letter of direction have one on record. A musician cannot judge the Act by ear, only by whether the paperwork behind a track is in order before it streams.

• Is this recording's musical work registered with the MLC under matching title and writer credit?
• Does any producer, mixer or engineer on the session have a SoundExchange letter of direction filed?
• If the recording predates 1972, has its distinct federal status under Title II been checked?

The Music Modernization Act is infrastructure, not doctrine. It says nothing about what a musician may claim to have authored with AI assistance, only how the royalties for whatever is claimed get collected and paid. That distinction matters more as more releases carry some machine-made element into the same payment pipe.
