I mean, how the songs correlate to each other, how thematic they are and how well the transitions sound. Like, it's clear they don't add in random songs just to appeal to everyone and it is gorgeous. I wish they had the same approach to their main albums as well, but they are still on the stage where they have to pull new audiences in, they're still growing and some songs just sound like they don't belong to the same album... P. S. I hope RM submits his album to Grammys. It's less likely to even get a nomination, but you never know... I think it's my favourite bts album outside tear. P. P. S. Blueside and badbye are masterpicies.
