The K-Pop thing is still a little foreign (no pun intended) to me, but the success of BTS is insane. These guys are crushing it. I get about 50 tweets a night from the 'BTS Army,' who I'm sure would give their own lives for BTS. It's a Beatles-like following, which was the theme as they performed on The Late Show With Stephen Colbert last night. The Ed Sullivan Show was a little before my time eve, but this is pretty cool...
