Yeah, well I feel that J-pop doesn't have a characteristic face anymore
To me, it used to be ayu, kuu, utada, namie, and even BoA... But some of them are gone, others lost their popularity, and I dunno.
I'm always gonna love and support ayu, I'm in for her all the way through and hopefully that's never going to change, but she's not the face of J-pop anymore, which is not sad but perhaps a bit nostalgic.
I also miss Leah Dizon, sifow, and I dunno, many others who disappeared with time...
The boy and girl groups are infectious and annoying, I hardly got into AKB48 but got over them rather quickly... There isn't much to them, just money and overzealous fanaticism.
