Mabel Ramos’s favorite song is “Ghostbusters” by Ray Parker Junior. From morning until night, if Mabel is awake, she is listening and dancing to—or asking to listen to—the number one Billboard hit from 1984. Though some parents might be annoyed by listening to a single song repeatedly, her father, Mark Ramos, said he is delighted by his daughter’s ability to dance, communicate and express her enthusiasm.
