Why don't you just go to yesasia.com, or brand-x, or closet child... or, third stage?
I buy from yesasia.com and brand-x. Infact I just sent in my IPMO to brand-x for Asagi's new set of perfumes

I love Corvinus.
to things back on topic though; whiny singing voices don't bother me. I like Miyavi's voice 80% of the time. Gara is another singer that people sometimes love or hate. I love his voice tho. I don't know; Miyavi is like average to me in the singing arena. It's tolerable. If he was really really horrid; it would ruin the music for me. Kinda like whoever was singing for Ruiza's second mini album.
