Hey everyone, I'm also interested since I only listen to j-rock, not j-pop
I have a few songs that you didn't mention, I'll look through my library and list them when I have time (give me a few days, cause I'm leaving in a few hours), so I can share if you want them. I'd also pretty much like to steal some of the songs you mentioned ;P
If you're interested in Gackt, I've made his Another World for Ultrastar and I think it came out fine, and I'm in the middle of making Seki-Ray. I wanted to make Redemption, but the midi I got was worthless :/ I'd also kill for a good midi of Lu:na...
Akiharu, and everyone else who would be able to help, really, could you please share those sheets? I'd be happy to create these songs. Generally, if anyone has midis or sheets (so far I've used midis, but I hope I'll manage to create songs with sheets too) for bands like The GazettE, Girugamesh, D'espairsRay, Abingdon Boys School, Gackt, Miyavi, Hyde, Vamps, LM.C, or something similar, I'd be more than happy to work on them and share what I can come up with. Most interested in Gackt and D'espa.
(please no Dir En Grey, with all due respect I have to be able to listen to it to make it. Don't get me wrong, I've a lot of respect to this band, but I can't stand the music ;P)
