I Have a Question

Tonight on West Wing there was a repeat of the story where the NASA administrators lobby Josh about funding a trip to Mars. He, of course becomes enamored with all things space, and at the end of the episode talks about the Voyager probe.

In trying to make expenditure on space research feel closer to the heart he talks about the recordings that are traveling with the space probe as an effort to try to tell alien cultures about ourselves. The story is about how the one artist died crippled and destitute, but his music had just left the solar system.

My question is this: If aliens make copies of the included recordings for their friend aliens, will the RIAA try to sue them?
