I just downloaded Skirt Hirari, my first PV of AKB48, and I admit that I didn't give a damn for the music at all. But my eyes were wide open for the upskirt shots
The music was forgetable, and most of the girls were as well. Don't mean to be negative though - one girl was cute, most others were just so-so. The upskirt shots were cute, but nothing special.
Did the cute girls showing their panties gimmic work to get me interested? Yes. Did it get me hooked? Not really....
Edit: the cute girl was Kojima Haruna. Damn she's cute.
