AKB48 - Labrador Retriever

I ordered 8 copies of the Regular Edition. I like the covers of the Limited Editons way more but I wanna have the photo and no Handshake ticket I can not use.
All in all the single is solid.
At first listen of Labrador Retriever I was dissappointed. But after many listenings it grew on me.

At first: I'm sad this single won't have an Undergirls Song. The graduation song of Oshima Yuko (Kyou Made no Melody) isn't my cup of tea. I don't understand the decision of using the song in every edition. I would prefered an Undergirls song. T__T

So my ranking of the songs:
1: Team A - Kimi wa Kimagure (finally a nice Team song of A. Shimazaki does a funny job in the PV. Her expressions are cute.)

2. Labrador Retriever - The song alone is okay. I wouldn't say it gives me the vibe of a summer song but the concept and the idea are good. Well about the center U can discuss a lot. Mayu isn't my favourite member.

3. Team 4 - Heart no Dasshutsu Game (Team 4 made a big step for me. They improved a lot and show their best. A big plus is the change of Rena Kato. Because of her I wanna know more of this "new" Team. The song is catchy.)

4. Team B - B Garden (If I hadn't watch the PV I wouldn't understand their speaches. ^^' I would love to see more focus on the Team and not the content of Mayu and Ikoma. They may the most famous persons in B but well not for me... :P)

5. Team K - Itoshiki Rival (nice PV and good concept of the PV but the song is kinda blank... I hear it and well forget. Haruppi rules in the PV and in some way I'm happy to see her in Team K.)
