For me, this single is so special. I admit it, i love almost every songs in this single.
Labrador Retriever is very different summer songs, but "Bokutachi no koi wo, zutto jirettaku" part is very good, and I prefer short ver. For MV, i just can't understand with Rena licking ice cream after it's been licked by dog before . Until now, I prefer kind of smooth and creamy color MV to create vintage atmosphere.
Kyou Made no Melody, since this song really like Omoide no Hotondo (1830m), i can't really judging it's good or not. Namida no Sei Janai it's very touching for me. And because this song filling slot for UG song, I think it's cruel for usual UG members, ufu. But because this 32-nin senbatsu, bunch of undergirls are entered senbatsu (as well Tentoumu Chu).
Kimi wa Kimagure is a simple rhytm and song, but because it's very simple and not tendensious like common idol songs, i like this one (and Sakura Miyawaki, also Paruru in MV mostly)
Itoshiki Rival at first I think will be boring song, but when I heard full.ver, this song it's just great. But, the idea of MV by try to standing a pole by 3 punky girls is just annoy me.
B Garden, with (really) repeated chorus and lines tone, barely can't get out from two tones, but I very like this song.
Heart no Dasshutsu Game is just common idol song you can found in new-idol-so-ever group in Japan. It's happy (the song structure reminds me of Hanamichi Ambitious), genki, and soft. Same atmosphere we saw in Seijun Philosophy. It's a okay song.
Futari wa Dekiteru by Kojiharu and Kitagawa Kenji is good adult-ish idol song you can find in any SDN tracks. Because of their performance in last Kouhaku, it's really worthy to hear the full version.
One problem, too many safe songs. Almost all is okay songs and I can remember and forget easily. Compared with Sayonara Crawl, at least this single have more good songs. But Bara no Kajitsu is unreplaceable.
