Mechanical royalties are one of the oldest royalty types in music, and also one of the most misunderstood in the streaming era. The name comes from a time when songs were reproduced “mechanically” onto piano rolls and records. The concept survived intact: any time your composition is reproduced, a mechanical royalty is owed — and in the streaming world, reproductions happen constantly.

This guide explains what mechanicals are, what triggers them, and how an independent songwriter collects them. Because the exact amounts depend on platform, territory, and your splits, we keep this qualitative and point you to the Publishing Royalty Recovery Diagnostic for a sourced estimate based on your situation.

What a mechanical royalty actually pays for

A mechanical royalty is paid to the owners of the composition — the songwriters and their publisher — whenever that composition is reproduced. The classic examples are physical (a CD or vinyl pressing) and digital download. But the crucial modern case is streaming: each interactive stream involves a reproduction of the song, so it generates a streaming mechanical alongside the recording-side payment.

This is why mechanicals matter so much now. Even an artist who never sells a physical copy can accrue meaningful mechanical royalties purely from streaming, provided they’re registered to collect them. To understand why the composition is treated separately from the recording, see Music Publishing Explained.

Mechanicals vs. performance royalties

Mechanicals are easy to confuse with performance royalties because both come from the composition side. The difference is the triggering act:

  • Mechanical royalty — triggered by reproduction (pressing, downloading, the copy made during streaming).
  • Performance royalty — triggered by public performance (radio play, a venue, TV, the public-performance element of streaming).

A single stream can generate both: a mechanical for the reproduction and a performance royalty for the public performance. They’re collected by different bodies, which is why you generally need to be registered in more than one place. Performance royalties flow through PROs — see Choosing a PRO.

Who collects mechanicals in the US

In the United States, The MLC (The Mechanical Licensing Collective) is the body responsible for collecting and distributing streaming and download mechanical royalties for songwriters and publishers. It receives data and royalties from the streaming services, matches them to the correct compositions, and pays out the rights-holders.

A few important facts:

  • Registering with The MLC is free. You don’t need to pay a third party simply to access mechanicals owed to you.
  • You have to register your works and match them so the MLC knows the royalties are yours. Unmatched mechanicals sit unclaimed.
  • The MLC handles the composition side. It does not collect the recording-side digital performance royalties — those go through SoundExchange. We lay out the difference in MLC vs. SoundExchange.

We walk through the sign-up process in How to Register With the MLC.

Physical and download mechanicals

Streaming gets the attention, but mechanicals also accrue from physical product and permanent downloads. If you press vinyl, sell CDs at shows, or sell downloads, mechanicals are owed on those reproductions too. For self-written, self-released music you effectively pay them to yourself, but the obligation matters the moment someone else’s song is involved — for example if you record a cover. Distributing a cover legally means clearing the mechanical for the song you didn’t write, which we cover in How to Distribute Cover Songs Legally.

Why mechanicals go uncollected

Mechanicals are a classic source of money artists leave on the table, usually for one of these reasons:

  • No registration. If your works aren’t registered and matched with The MLC, US streaming mechanicals accrue but don’t reach you.
  • Only the writer’s share is set up. Mechanicals, like other publishing royalties, involve a writer’s and a publisher’s share. Collecting only one can leave the other behind — see Songwriter Share vs. Publisher Share.
  • International gaps. Mechanicals earned abroad are collected by foreign societies, and reaching them can require an administrator. That overlaps with the broader topic of collecting international royalties.

Unclaimed mechanicals can eventually feed “black box” pools, distributed by formula rather than to the artist who earned them — see Black Box Royalties.

Getting set up to collect

A reasonable approach for a self-published artist:

  1. Register with The MLC and match all your works for US streaming mechanicals (free).
  2. Account for both the writer and publisher shares so you’re not leaving half behind.
  3. Decide on international collection — self-administer or use a publishing admin to reach foreign mechanicals.

Because the dollar value depends entirely on your streaming volume, territories, and splits, the Publishing Royalty Recovery Diagnostic is the right place to translate “you might be owed mechanicals” into a structured estimate.

Frequently asked questions

Are mechanical royalties the same as the money my distributor pays me? No. Your distributor typically pays recording-side streaming revenue (the master). Mechanicals are a separate composition-side royalty, collected in the US by The MLC. You generally need both.

Do I earn mechanicals from streaming even if I never sell anything physical? Yes. Interactive streaming involves reproducing the composition, which generates streaming mechanicals — provided you’re registered to collect them.

Is it free to collect mechanicals through The MLC? Yes. Registering with The MLC is free. Be cautious of anyone implying you must pay just to access mechanicals that are already yours.

What’s the difference between a mechanical and a performance royalty? A mechanical is triggered by reproduction; a performance royalty is triggered by public performance. A single stream can generate both, collected by different organizations.

Do I owe mechanicals when I record a cover song? Yes — the songwriter of the original is owed a mechanical when you reproduce their composition. Clearing it is part of releasing a cover legally; see How to Distribute Cover Songs Legally.
