10:35-ish to 12:40 in Art of Life. I stop everything I'm doing and take all of that in. I just think it's breathtaking. The orchestra with the guitars and--- Ahh, I just love it, it leaves me shaky sometimes.
(I'm lame, I know.)
Not sure if it counts as a solo or interlude, but in Forever Love Acoustic Ver., starting at 4:37, just Toshi singing and nothing else is so beautiful.
The end of Say Anything with Yoshiki speaking, the piano, the orchestra..
Celebration's guitar solo just gets me all pumped up for some reason. It just makes me want to dance a little. xD
Aaaaand, probably a hell of a lot more, but I can't think right now.
