I don't consider it KPOP. To me, KPOP is a mixture of dancing and singing simultaneously and doing these things on stage. It also has a distinct sound since there are other K-genres in music that are considered separate from KPOP like K-rock, K-bands, K-rap, etc. So I always considered OST songs being different since they're made for the sole purpose of a K-drama or K-movie.
Okay! Hopefully, I can remember myself
(jk, I'll write it down somewhere)
LMAO yeah that is a ways away though so I don't blame you
