In the mid to late 90's, due to media consolidation for the most part, you had a huge influx of one-hit wonders. I mean, I'm sure you can think of about 30 from a 5 year period. But, there was a diversity of hits. Ska, rock, pop, punk, rap, R&B. Even latin and metal. I don't think the Korean pop scene has any of that. Maybe it will come in time, but not right now. I'll be honest, I got a little vicariously embarrassed for them during the Letterman show performance. When you take this out of the context of the Korean pop scene, it's really apparent just how far behind they are as performers compared to popular Western acts, in my humble opinion.
