Cinderella and the Prince

Today Anne was asking to listen to music.  She asked to listen to the song Cinderella by Steven Curtis Chapman.  I was going to start it, but for a moment I blanked on who the artist was.  I said, "Who is that?"  Anne replied, "Cinderella, Mom."  I said, "Yes, I know, but who sings it?"  Her sure reply, "a prince."  Why wouldn't the song "Cinderella" be sung by a prince?
