What I would do is just go ahead and copyright it now through the US Copyright Office (assuming you're in the USA?). It's easy and you could actually use a copy of the recording you just made (you have to send a recording - cassette or CD - of the songs you want copyrighted). Although it takes several months to get copyright confirmation, the material is copyrighted from the date it is received at the Copyright office. I doubt if anybody will rip off your songs within the next couple of weeks unless you flood the market with the recordings. I would not give out copies of those recordings, however, untill you've sent off those copyright papers. At this point you probably don't need to worry about ASCAP or BMI, but go ahead and get your copyright.
