Interesting that they say they "require" stations to submit playlists. Of the eleven stations I polled in my immediate area when releasing my CD, none confirmed that they report to anyone.
I am an ASCAP writer and publisher. I only deal with BMI when licensing; however, the info you provided still confirms what I said. They don't pay for every play. Which reinforces what I originally told Tom, Properly registering your works doesn't guarantee payment, but not registering guarantees that you won't get paid.
