Kyon sure has a lot to say. In fact, from what I can tell, they're making use of the fact that Kyon time-travels a lot and ends up interacting with himself often, so there are many versions of Kyon singing the songs. Addition of short but original chorus by Haruhi (Aya-chan) for the first song spices things up, too.
I must assume this is the last one. I mean, if they wanted to release CDs for Taniguchi and Kunikida, I'd think they'd have done so before Kyon. Then again, who knows? How about Shamisen's single?
Another exclusive fixed-up fully unfolded jacket scan. I think Haruhi is forcing him to make an appealing pose. Obviously, he's not very successful.
