TV in Japan

This is SUPERBELL"Z, who have produced many albums in this genre with all lyrics either taken directly from train announcements or closely related. Their stuff is really catchy. I heard them first when some friends selected a couple of their tunes during an all-nighter at a Pasela karaoke place.

I've picked up a couple of their albums and I recommend 「MOTOR MAN Vol．Ⅱ(大阪編＆上野発最終便)」 if you can find it.
