BMI's site is for registering songs so you can win in court if someone steals your song, right?
No, that's not it. What you are talking about is the Library of Congress and registering your copyright - entirely different.
BMI is a performing rights society. They collect and distribute performance royalties based on cue sheet submission and survey.
Which is to say, if you are a BMI member and you write a song and register it with BMI, and then the song is performed in public (e.g. TV, radio, etc) and the song usage is properly reported, you get paid a royalty.
As touched on earlier, you must think of a song as pie - the song writer owns half of the pie (draw it, it's fun) and the publisher of the song owns the other half of the pie. That is cut and dried - it is that way for all songs that are published - 50% owned by writer(s) and 50% is owned by publisher(s). Now, within each of those 50%'s - it can be broken down further. 2 writers can split that 50% how they see fit and same goes for publishing. Does that make sense? So, let's see... as an example.
Me and Joesph Q. Blow write a song together. Joe wrote music & lyrics and I just wrote some of the music for the bridge and chorus. Joe and I discuss it and decide that he deserves more writing credit than me, and that is fair with me. We both own our own publishing companies, so we do the same thing with the publishing. There are no set numbers (except that total writing credit equals 50% and total publisher shares equal 50%) but the actual breakdown can be decided by the people involved.
So, here is the breakdown afte Joe Blow and I discuss it. Let's say:
Writers
Brad (BMI) - 20%
Joe Blow (BMI) - 30%
Publishers
Brad Music (BMI) - 20%
JB Music (BMI) - 30%
Now, the song gets performed in Podunk, Mississippi on a radio station that broadcasts to a population of 17.
The radio station submits a cue sheet that states our song gets played.
BMI decides, based on scales and shit I know nothing about (it has to do with market shares and demographics and surveys and statical probability and blah blah blah) that my one play in Podunk is worth $1 (Yeah right! More like 1 penny, if that - but a dollar breaks down nice for purposes of example)
So BMI now makes sure that Brad the writer gets 20 cents and Joe the writer gets 30 cents. And they make sure that Brad Music gets 20 cents and JB Music gets 30 cents.
We own our own publishing, so we get the whole shebang. I get 40 cents, Joe get 60. That fucker! Oh, wait - this is make believe.
Anyway, that is what ASCAP & BMI do for the most part.
Holy god, why did I just type all that? What was the question? Where am I?
Who are you people?
