Is it really kpop anymore when your songs are fully english?

Depends, despite bp having 3 good english speakers they still speak in broken english so I wouldn't count it.

Bp is one of the only kpop groups for who it actually makes sense to sing in English. But I don't really understand why kpop stans get so mad about this. You're sounding like koreab0os who love all things Korean and think everything is better in Korean.
