I recorded this video the last time my wife and I were visiting her family. I'd keep hearing music that was like an ice cream truck, only with lyrics. I asked my wife and she said that they were vans selling cooking gas. In the summer, they sell sweet potatoes. No ice cream trucks in Japan. Go figure. Your options are gas and sweet potatoes. This truck was playing a song thanking people for their business.
Had to ask the missus what Baby Metal is. Her response: "It's an idol group. Their songs are like torture." In that case, I suppose it'd be like J-Pop group in terms of the cringe factor. According to my wife, nobody listens to a lot of those J-Pop idol groups or goes to their shows except creepy men (surprise, surprise). Thankfully, she deplores J-Pop and her comments about it never cease to amuse me.
@JazzDad, how the hell do you know all of this random stuff? We need to compare notes someday.
Even creepier than Dr. Smith. They're creepy by Japanese standards. Weapons-grade creepiness that'll make you cringe so badly that people will think that you're convulsing and doesn't make your skin crawl; it makes it run full-tilt. Your skin will crawl so badly that it'll outrun The Flash.
Me personally, I prefer Osaka Monaurail or Sadistic Mika Band/The Sadistics. Actual musicians and not just some cutsey stage show.
