Atlus goes disco with a new Persona Dancing all Night trailer

Atlus has a mad 30 hour Niconico marathon going on in Japan, for all the Persona games. Popping out of that is a new trailer (more of a song really, the main theme apparently) for the upcoming disco frenzy that is the Dancing All Night experience, due out this year, which will have to do us until Persona 5 Golden emerges at some point.
