If you write songs, affiliating with a Performing Rights Organization (PRO) is one of the foundational steps to getting paid. But the moment you start looking, you hit a wall of options — ASCAP, BMI, SESAC, GMR — and a lot of strong opinions online. This guide explains what a PRO actually does, how the main US options differ, and a sane way to decide.

A PRO is only one piece of the royalty puzzle. To see the full picture of what you might be missing, run the Publishing Royalty Recovery Diagnostic.

What a PRO does

A PRO collects performance royalties on the composition — your underlying song. Performance royalties are generated whenever your song is publicly performed: played on the radio, performed live in venues, used on TV, and streamed (streaming generates a public-performance component too).

The PRO licenses your catalog to the businesses that perform music, collects the fees, and distributes the resulting royalties to songwriters and publishers. Without a PRO affiliation, performance royalties on your compositions generally won’t reach you.

Crucially, a PRO does not handle everything:

  • Mechanical royalties (streaming reproductions) come from The MLC in the US — separate registration.
  • Sound-recording royalties (the master) come from SoundExchange and foreign societies.

We map all of these in MLC vs. SoundExchange. A PRO is necessary but not sufficient.

The main US options

There are four US PROs, and they fall into two groups.

ASCAP and BMI are the two large organizations that most songwriters consider first. Both are long-established, both collect performance royalties broadly, and both operate on a model open to independent songwriters. For the majority of indie writers, the practical choice comes down to one of these two.

SESAC and GMR are smaller and operate on a different, more selective model. They are generally invitation-based rather than open to anyone, so for most independent artists just starting out they aren’t an option you simply sign up for the way you can with the larger PROs.

Because of that, the real day-one decision for most independent songwriters is ASCAP vs. BMI.

How to think about ASCAP vs. BMI

Rather than chasing claims about which one “pays more” — payout depends heavily on your specific performances, and the organizations distribute on their own methodologies — focus on factors you can actually evaluate:

  • Eligibility and joining. Check the current requirements and any joining fees on each organization’s own site, since these terms can change.
  • Membership structure. Consider how each handles writer and publisher affiliation, especially if you’re self-published and need to account for both the writer and publisher shares of performance royalties.
  • Tools and reporting. Look at the member portals, how works are registered, and how clearly you can see your statements.
  • Fit with your ambitions. If you have specific sync or international goals, weigh how each organization supports those.

There is no universal “best” PRO. Many successful writers are with ASCAP; many are with BMI. The bigger risk is not which one you pick — it’s failing to register your works properly once you’ve joined.

Don’t forget the publisher share

This trips up self-releasing artists constantly. Performance royalties on a composition have two halves: the writer’s share and the publisher’s share. If you’re self-published (no separate publisher), you may need to account for both halves yourself. Understanding this is part of not leaving money uncollected — see the Unclaimed Publishing Royalties Guide.

Where a publishing admin fits

A PRO handles domestic performance royalties on the composition. It doesn’t solve international collection or YouTube Content ID, and it doesn’t cover mechanicals. A publishing administrator can layer on top of your PRO to handle registrations across territories and chase royalties a solo artist struggles to reach alone. Whether that’s worth the commission is a real decision, covered in Publishing Admin vs. DIY.

A practical sequence

  1. Pick ASCAP or BMI based on current eligibility, structure, tools, and fit — don’t agonize.
  2. Register your works with your chosen PRO. This is the step that actually gets you paid.
  3. Cover the other pools: The MLC for mechanicals, SoundExchange for the master, both free.
  4. Decide on administration for international and Content ID gaps.
  5. Run the diagnostic to confirm you haven’t left a pool uncollected.

Frequently asked questions

Which PRO pays the most? There’s no reliable universal answer — payout depends on your specific performances and each organization’s distribution methodology. Choose on eligibility, structure, tools, and fit rather than payout claims.

Can I join SESAC or GMR as a new indie artist? Generally these are invitation-based and more selective, so most independent artists start with ASCAP or BMI.

Can I be in more than one PRO at once? You typically affiliate as a writer with one PRO at a time. Review each organization’s current terms before joining or switching.

Does my PRO collect my streaming mechanicals? No. Mechanicals in the US come from The MLC, which is separate and free. See MLC vs. SoundExchange.

Do I still need a publishing admin if I have a PRO? Not necessarily for domestic performance royalties, but admins help with international collection and Content ID. See Publishing Admin vs. DIY.
