*d4* by blackpink was the song that introduced and got me into kpop, i.c.o.n.i.c. omg and *stereotype* by stayc was soty 2021 for me. aaand i'm so happy you included *bon bon chocolat* by everyglow, still the *best 4th gen gg debut* idc
btw wonderland by ateez has a special place in my heart since i finally saw them live a few weeks ago and they opened with this song and i almost fell of my chair lmao i was standing for the rest of the concert cause their energy was outstanding :)
I agree with all your picks but for BTS i think it's Blood sweet and tears and for StayC i think it's Asap. Also for Fromis_9 i think it's Love Bomb. But all those songs are amazing anyway !!
I would have liked if you put for fromis_9 love bomb instead of fun. I remember kpop fans sobbing in the comments about how that song reminded them of something nostalgic.
