This is actually the second in a series of Touhou Arrange CDs for Birdtune. The first one, 「東方ちゅんちゅん郷」, came out mere months ago at M3-24, so odds are it is still available for sale. As of this post, samples for the second album weren't available, but you can check out the first to get a pretty good idea. IOSYS take note: this is how you do a GREAT Touhou comp! No more filler bullshit, plzkthxbai.
UPDATE: Due to manufacturing problems, release of this album has been postponed to Reitaisei 7 (March 2010).
