V-kei: why they must sing?!

Hey everyone! I thought my second post will be tomorrow, but it's stronger than me. And I have a little question to all of you guys, who like j-rock and visual kei. Do you know MEJIBRAY? What do you think about that? Today it was first time I listened some songs of this band and I think I fell in love :p They present style I like very much. Their music is a little bit similar to Awoi, what is fantastic, because Awoi is one of my favourite bands ^^

One sample of their music:

Quite nice, huh? Yeah, I know, it is :p Really interesting.

Today I have "visual kei day". I was writting post about v-kei make-ups on my another blog, so maybe that's why. Btw, I haven't listened to j-rock for a while and now I feel I discovere it again. I like doing a little brake in visual kei sometimes, because when j-rock comes back to my headphones then is much more... fresh? Interesting? Hm, something like that :P I'm sure you know what I'm talking about.

Gif for Uruha's fangirls :p

Sometimes I think he's too hot. The Gazette is not my favourite band but Uruha... yeah :3

Btw, sometimes when I listen to j-rock I think Japanese guys can make really, really interesting music. But only music. Vocal usually... sucks! I mean the song would be much better without vocal or with another voice. Usually songs start with lovely and strong guitars, sometimes I think it will be very heavy song, but when vocalists start sing music is slower and in general everything is lighter (is that good definition for not heavy music? :P). Why japanese vocalists must sing in heavy songs?! I don't get it. They have fantastic voices but songs are quite boring because of their singing sometimes. I love their growls, so deep and hard growls. I think they really should growl when they play metal.
What do you think about that?
