Thanks for the nightmares....
I haven't listened to RunRoze yet, but I'll just review the piece as in. Why did I choose to listen to this track at night, I do not know...<_<...>_>
I'll start with the intro. This part is definitely my favorite. It definitely gave me the creeps when listening the first time around, and even the second and third. I think the what made it so effective was probably the random voices in the background in combination with the lone melody. Personally, I think the static at 0:33 was a bit loud, masking the creepy scream a little too much.
0:49 - Wait, what happened? I find the lack of a transition here quite disappointing. One moment, I'm watching zombie children eating a corpse's guts, and suddenly, I'm running out of a hotel infested with undead. It was just far to sudden for my liking. Aside from that, I actually enjoy the beat, fitting for a zombie apocalypse. Plenty of distorted and disturbing sounds. I think in this part you could have added some sfx though, maybe a maniacal laugh or something. Like the one at 1:53
2:06 I personally think the voice doesn't go very well with rest of the instruments. The voice is sinister and secret, but the beats are scathing and slicing (alliteration unintended). I think you could have defaulted back to creepy background noises and/or a soft lead to complement its creepiness. I like the lyrics, though, they fit very well with the theme of the song. I like the fade out at around 2:50, it really brings out the creepy voice.
Ending - Freaking. Amazing. Basically gave me as much reason not to go to bed tonight as did the intro. I liked all the noises coming together on this on.
Overall, I don't think I'll sleep well tonight. Good work!
