From “Friday” to “My Moment,” Black — who, lest we forget, is just 14 years old — moved away from the ridiculous Ark Factory anthem the world fell in love with (making fun of) and put out a pretty boring pop song about hating haters.

But now she’s returned to form with lyrics that include:

“There’s a chalk line on the dance floor/ In the shape of my heart/ Crime scene tape on the front door/ And you are a person of interest.”

Get it? Her heart has been murdered by a little thing called a crush. (“Can't say that it's love yet, but somebody's obsessed.”) I’m betting the suspect is a pretty good dancer.
