Yep Sousei is definitely a good one.
Strange though, I wonder if I'm the only one who likes "Futari" The way it starts out slow and heads upwards to a climax near the end. In contrast to the more upbeat Natsukage, I can tell there is a bittersweet melancholy feeling coming from Futari.
I guess it was noteworthy enough that they turned it into a song for the AIR movie's ending, which I happen to like as well
