Hey guys, I'm not sure if this is even the right place to post this,but I have a question. I have an original song that deals with exorcisms so naturally at the beginning of the song I put in a quick sound clip from The Exorcist of Reagan quoting "What an excellent day for an exorcism". The quote is mixed in with a few other noises that I added just to give it more of a "scarier" feel, but my question is, are short quotes like this considered "public domain" and I can I get away with using the clip just once during the intro of the song? I don't know if any of you guys have ever run into this, but any input would be appreciated. 
Unless you are planning to release it for monetary purposes I don't see a problem.
Yes I am guitarded also, nice to meet you.
Here is another thought. Make a recording of a woman saying the same line in a similar way. Import it as a .WAV file into Audacity and use the pitch corrector (under effects) to take it down to about -40%. I just tried it and it works well. Now you have no issues at all.
