Japan's Biggest Sensation Dresses Like Sgt. Pepper On Friday The 13th

    Meet the all-girl Kamen Joshi, aka "Mask Girls," who just topped the charts in Japan.

    Earlier this year Japanese idol group Kamen Joshi, or Mask Girls, released a track, "元気種☆" or "Genkidane☆," which is now No. 1 on Japan's Oricon Singles Chart.

    Mask Girls are made up of three Japanese idol groups -- Alice Juban, Steamgirls, and Armorgirls. "Genkidane☆" is a Babymetal-inspired romp that switches on a dime from cheery positivity to hardcore, boot-stomping metal.

    The lyrics in "Genkidane☆" are designed to inspire -- pump you up, get you excited about life. Kamen Joshi are basically singing random positive phrases. The song's title means "happy/energetic."

    Kahn helped translate some of the song's lyrics, which alternate between Japanese and English, to help us nail down its basic theme.

    After all that sunshine comes a dark cloud by the way of intense guttural screams and a dramatic shift in mood to wash away whatever posi-vibes the song's beginning may have built up.

    Then it's back to Pleasantville... a Pleasantville stocked with teenage Japanese girls dressed like Sgt Pepper ballerinas who were put on earth to do the bidding of Jason Voorhees.

    The song continues: "Scream it to the sky every day! [In English] Rock this valley! Scream it again and again so it resounds! [In English] Rockin' Body!"

    "Today you're a small seed/ Show off how important you are/ Don't be afraid, go forth confidently into the unpredictable world!" they sing.

    Words to live by.
