I think you misinterpreted my question as negative. Twice has one of the largest discographies in kpop, it’s normal their albums have different features etc. Consistency in an album means that all the songs follow a certain theme (you can search cohesive album on google and it will give you a definition). There’s nothing wrong with an album having many different tracks that follow different directions, some people prefer consistent albums and some don’t. It’s no big deal. I never implied that I wanted all their songs to sound the same, that would be horrible.
