Here's a probably unpopular opinion: I really don't care and would rather not have Japanese artists getting into the American/Westernwtvr scene, or being somehow validated by it. I don't understand why so many J-fans want /need/ this to happen and are constantly blathering about how they could achieve this. Most US releases, as in albums geared towards the US market like the English VAMPS album are so godawful and I'm just like, why.
I prefer Japanese music, it's 90% of what I listen to, I don't need it or want it in a music market I don't even like. And I don't need anyone to validate my music tastes either.
