KAR-742 - Lingerie Shop Fitting Room Voyeur 2: 60 Local Beauties Exposed

It's inevitable that this series reuses the same cast from the previous Karma hidden-camera series. But they feature women who are a bit plain or have a 'hard-luck' look, and since they feel so much like real amateurs, I personally like it. However, what is up with this electronic-sounding BGM? The production is good enough that it didn't need any extra fluff, and the music is ruining it. So, I'm deducting one star.
