Yes! They are publishers (administrators). Some companies are offering this kind of service (CD Baby PRO and others), but i heard that some of them (CD Baby PRO included) uses Songtrust´s system.
If you don’t have a publisher, you are your own publisher (with 100% of copyright). The publisher, as you probably know, will search (Songtrust specific: including direct tracking your music with more than 45 PROs around the world - BMI / Ascap included), administrate, collect mechanicals and sometimes even increase exposure of your music (if you agree before).
PROs have kind of a gentleman’s agreement about foreign PROs performance rights. They (Songtrust, CD Baby Pro and others) say that they will go beyond that. Doing something called “direct registration”. From CD Baby´s Pro support page:
"## 2. Performance royalties from overseas: reciprocal agreements vs. direct registration
ASCAP and BMI will absolutely collect these royalties for you. That’s why those organizations exist. But they do NOT register your songs directly with foreign royalty collection societies. They rely on something called a “reciprocal agreement.” You scratch my back; I’ll scratch yours.
When you sign up with CD Baby Pro, we will register your songs directly with foreign societies, ensuring that international performing rights organizations know about your songs, have all the correct data, stay on the lookout and accurately tally public performances (by which I mean any of the usages mentioned above), and know exactly who to pay.
You don’t want to leave something like royalty collection up to chance. CD Baby Pro ensures that foreign collection societies WILL know about every one of your songs. In most cases, when we directly register your music with foreign societies, it also means you get paid your publishing share roughly 3-months faster than you would when relying on your P.R.O. — and without additional fees incurred between P.R.O. reciprocal agreements."
As i said, mechanicals aren’t the main thing for us, but probably we have those also (if our song is out there on media). It´s not only about cover tunes. It is also about downloads, selling CD (many films sells CDs and / or put on streaming), and even one part of streaming rights are also mechanicals (so maybe we’re looking for performance rights on streaming but we also have mechanicals to receive).
eg. If an indie movie uses one of your tracks and they sell DVDs, guess what? You have mechanical rights to receive from every and each sale.
If there’s a product that uses our music, we probably have mechanical rights to receive there. CD, DVD, download, streams…
The term “mechanical” and “mechanical license” has its origins in the “piano rolls” on which music was recorded in the early part of the 20th Century. Although its concept is now primarily oriented to royalty income from sale of compact discs (CDs), its scope is wider and covers any copyrighted audio composition that is rendered mechanically; that is, without human performers.
Again, its not the “main thing” for us, but if you have even $50 of mechanical rights to receive, which are yours by right, why not?
