Solution

Well, Faith has not given up on her "porn music" so her dad has taught her something new that seems to be sticking. Instead of her saying "bow chicka wow wow" she now says "bird chicken cow cow."
This morning she was saying that and asked me if I could show her a picture of a birdchickencowcow. Last week we had looked up pictures of an armadillo. She must have heard it on tv at daycare. She likes to find things on the computer.
