It used to be really mainstream here, at least in my country. You will see school kids covering the dance everywhere and the popular groups' songs will be everywhere. I never miss their cb because of this. But for these past few years, I feel like my stuck in the 2nd and 3rd gen eras. In the radio and malls, if they play kpop songs, it will always come from those older groups. Again, I never missed Bts or Bp cb because of this. The only 4th gen songs I heard this year on my local radio station and most places are cupid and newjeans songs. The other new songs are only flower and bts solo songs especially seven. The younger kids that I know mostly only know Bp and Bts when I ask them about kpop.
I am probably the only one that feels this, but I certainly feel like in a few more years, kpop will start to be non-mainstream again in my country. My local people know Bts and Bp members' names yet still think that every bg or gg is them. We still have a lot of kpop fans here stanning the new generation groups but kpop really feel and look not that popular anymore like before in my country.
