I think this one is probably my most favourite Spitz's album.  I can't find any songs that I may not like in this album.  It may be because I love "Spider" and "Aoi kuruma" too much.  "Sora mo toberu hazu" is also a very good song. I love the female background vocal in "Hemachi no hana", and it is one of the sweetest tracks in this album. "Koi wa yuugure" is another beautiful love song.  However, for "Koi wa yuugure", "Raspberry" and "Fujimi no Venus", I do prefer the orchestra versions in their first concert video. Japanese fans should understand the lyrics in "Raspberry" very well. "Tada kimi no nude wo, chanto miru made wa boku wa shinenai." (I can't die without seeing your nude body.) (^^;) (Hahaha...)

On the whole, you will find that the Spitz world is incredibly huge and interesting, and you may be able to find your own "sora no tobikata" (the way flying to the sky) after listening to this. (^^;)
