BMI vs. ASCAP?

[Bill Gribble]

I give up trying to look at the applications and figure out which one
is which.  There are these songs, they are on a record, I want to
collect the big $$$ when they break the Top 40, and I have no
publishing affiliation... which one of these do I pick, and which
forms do I fill out?

Thanks,
Bill Gribble
