How many pron movies use exrpessly cmposed music. It seems they simply use program stuff and tat is the end of it. And, I am not expert but, does the composer actually get credits. I guess they do. So the questions is, when the Feds bust the operation, are you part of it? It seems the ocmposer is too remote and could easily claim that he did not know what the music was used for. I guess your not a pronographer unless you think of yourself as one. Pronography is in the mind of the beholder.
The real problem is the subtle references in this thread to the incredibly cheesy music that goes with porn. Imgine being interviewed for a real music position, would you want to put "porn composer" on your resume?
Just some thoughts.
