Yoo I have no idea about K-Pop but this happened to me today and I guess I'l post it here:
Heard the popular Hot Summer on the radio today (it's about to get pretty warm here in Germany in the next week). The song is by Monrose, a band nobody outside of Germany should know about.

However, the moderator on the radio mentioned there's a K-Pop cover? I googled it and a band called f(x) covered it! How crazy is that? (BTW: Do they like math or statistics or what lol.)

That's all.
