A-side ranking for 2015 (so far)

• Koi Dorobou
• Otome no Gyakushuu
• Nen ni wa nen
• Yuugure wa Ameagari
• Ima Koko Kara
• Itooshikutte Gomen ne
• Tsugi no Kado wo Magare
• Taiki Bansei
• Ca va Ca va?
• Gamusha LIFE
• Survivor
• Wonderful World
• Seishun Kozou ga Naiteiru
• The Middle Management

Feels like blasphemy haha. Taiki Bansei would be much higher in this list if they didn't frick up the recording (way too autotuned, and I mean the real autotune not the voice effects, as if only 2 people were singing the song). Otome no Gyakushuu was on point, though. Kana's deep voice, Takechan's and Ayacho's whispering, the overall atmosphere... 100 points.
°C-ute was solid, but The Middle Management is so not my kind of music (I do love Nacky, but... I don't need that kind of song), Gamusha LIFE was a bit of a lackluster (I know, looking back etc., the anniversary song), but Tsugi no Kado wo Magare is a lot better.
Country Girls might be the big winners here since I actually do replay Koi Dorobou and Itooshikutte quite often.
Juice=Juice... don't know, that single was pretty forgettable for me.
I've said too much about Seishun, I think I shouldn't say anymore about it lol. Yuugure is a great song, close to TokiSora. Ima Koko Kara is standard stuff and might be boring to some, but I enjoyed it quite a lot. It's just a bit short.
I didn't like Survivor that much, but Nen ni wa nen was pretty awesome.
