I just heard of Perfume because of Yandere Simulator I mean I love them now I couldn't get the song put of my head!! I mean I love J-pop and K-pop but Perfume's Chocolate Disco is my favorite ❤️❤️
Also, not every japanese singers have computer-synthesized voices... like Megumi Hayashibara and Maaya Sakamoto. I love Perfume anyway, and I also like SNSD for example.. they are just different, that's all.
I feel sad for them for not being able to sing live( not in a mean way) I hope Nakata Yasutaka will make a solution for this. I know it's hard to process their 3 voices wireless and live by vocoder or autotune or whatsoever.
