You always come up with such great questions! xD And, though it's late, I hope you have a Happy New Year too! ^^

Let's see...music that I would recommend to Gackt? Enya. I recommend her all the time. Her music is just so soothing, it could put you to sleep. In the good way. And, her music works wonders for background noise when doing work or studying. The style is just so relaxing, nice and calming, which I think Gackt needs every once in a while, ne. ^.~
