I can... sort.. of understand what you're saying. Although I don't agree, I see your point. Miyavis whole conceitedness has grown and he has turned into a selfish, own persona loving, verrry childish bishonen. I personally love this!

I just can't get enough of his wierd expressions and dances. I could... agree that there probably people out there who are more talented than him, but he IS actually quite talented himself: he's good at guitarr, and he has a special, own voice. as for the voice, I guess some love it and others can't stand it. And... Miyavis looks are really just perfect. Try to find ANY flaws on the man and...well.. you wont! I can really understand WHY he loves himself; he's gotten the perfect skinny body, perfect height (unusually tall for a japanese) and a very very feminine bishonen face. He's pure beauty. I can understand that if you don't like his personality though, you probably wont like the way he looks either.
I guess, what Miyavi's done, is he found a character that suited him, and found that it's working. He's got tons of fangirls loving his selfishness *don't look at me*, and I guess since he's noticing it's working, he's not gonna stop. All that fame also nurtures his ego...
As for his songs, I think they're fun. Miyavi changes a lot, and every new song he does has something new in it and a new style. The way he jumps from genre to genre makes it all very interesting.
I wouldn't mind having you hit Miyavi though - he could really need a good beating sometimes... XDDD
It's OK if you don't like Miyavi *tackles you* Although... (I don't know what's wrong with you)... haha!
