I totally agree. It doesn't really have to be a fast song, and the song I MOST connect with (The Final) doesn't have any screaming really (besides the one quick one), but his screaming has sooo much emotion behind it. Again, I'll bring up dead tree and Kodou. The two screams towards the end of Kodou...I can't help but shiver. They are my most favorite Kyo screams ever (does that sound weird?).
I can't help but pretend I'm the one screaming whenever that part comes around. I know I look like a freak. Ah well. There just seems to be so much feeling behind those two screams, and they are so perfectly placed within the song. I actually don't like the video because of that...the long pause ruins the intention to me.
But...yeah, hehe. Basically, I agree.
