In case no one had told you this yet, the beginning of The Hunger Games trilogy is a pretty grim scene. So it makes sense that the first music video for the movie, which is due in theaters on March 23, wouldn't be the kind of setting in which you'd want to have a toddler's birthday party. Nevertheless, singer Taylor Swift is there, singing a sadly optimistic song called "Safe and Sound," the first official release from the movie's soundtrack.
