Honestly, isn't it just a question of supply and demand? Obviously they are selling well. And can there be
too much of it, just because it's not japanese (or because it's korean? Idk).
If you ask me, no. You listen to what you choose. The rest is out of your hands. If there was a boom of any kind of music in my country/countries (Denmark, Sweden) I'd be happy if it was good music of course, but if it was music that I don't want to listen to, I don't.
These K-pop groups to me, are just catering to what the japanese always enjoyed; less than being about good music it's about
idols. How cute the girls/boys are, what they eat, their star signs etc. I think that's mostly what's causing their current boom, like how popular Morning Musume used to be. Also their songs can be damn catchy
