What part of a K-pop song ruins the whole song? (1 Viewer)

SM sometimes likes to combine two songs into one like SHINee Sherlock (Clue + Note) and SuperM One (Monster + Infinity), though, the reception to these or at least SM doing this hasn't been negative as far as I know.

I stand corrected. Thank you.

Well, I don't know what the general fan base's reaction was for Karma after it dropped, but, I was just surprised since the girl groups I was a fan of never had a mixed song as a comeback title until now.

Still, I wish the music and lyrics for Karma was unique and original.
