The 4th gen song is nice to watch, everyone looks very good. With glasses even more. The director also found a clever way to include some one eye shots (not really a fan of that). The song itself is a bit disappointing. I did like the preview, but I hoped it would be more than just repeating that preview three times and call it a day. The Under MV is visually pleasing, were it not for the editing. It's too quick! You hardly get the chance to see what or who is on screen. "Look, it's Chima, let's see her dance... oh wait never mind, there's Ranze, her visual expression is... I don't know because there is the next shot already." I think I need to rewatch this one at half speed.
