Nothing against him in that regard, as I never got around to listening to his music. I simply didn't like the way he carried himself back then, but they were all young, so it's something I can look past now.
I did however predict this being a thing he'd stoop to, as Gackt, HYDE, and other artists who went to make solo-careers at that time ended up, well, you know.....
If you're willing to give the dude a chance, I believe miyavizm, myv pops and miyaviuta can give you the best sample of what he was doing at the time. lots of great ideas, weird stuff and most of all free experimentation
