Just found some new samples:
These are from the sample library "Distorted Reality Volumes 1 and 2" by Spectrasonics.
1. "Requiem" from the "Gothic Choir" in "Spectrasonics Distorted Reality vol. 1" (Like i said, he does use their samples alot).
He used it to create the song "Nightmarish Walsh" from Silent Hill 4.
2. "Turntables" which is also from "Spectrasonics Distorted Reality vol. 1".
I believe he may have used this Turntable FX in "Tears of..." and several other songs, but i'm not really sure.
3. "OLDCHEEZ2 80" from Distorted Reality vol. 2 Disc 1" was used in "Fortunate Sleep - Noone disturb her dead"
4. "DARK BROOD" - Distorted reality vol 2. This one isn't a sample that he used, but it sounds incredibly much alike this three-note bass (

5. "DROWNING - Distorted reality vol 2. Again, this sounds like something he could've used but i'm not sure (Same video as before:

6. "DIFFRACTION" - VISTAS - Distorted Reality vol.2. - Heard in the beginning of "The reverse will"
along with
7. "SOLAR FLARE - VISTAS - Distorted Reality vol.2. - Also heard in the beginning alongside DIFFRACTION
8. "EXCAVATOR - MUTANT FX - Distorted Reality vol. 2 - I'm not sure about this one, but something tells me that i've heard it before in either Silent Hill 2 or 3...
That's about it. I've looked through both libraries now.
PS. I must apologize in advance for being off-topic, but in the "Distorted Reality vol. 1" pack, there are plently of samples that was used to create the Zerg themes in Starcraft 1 and there are also several samples that were used in Final Fantasy X-2 and Advent Children and one for Metal Gear Solid 3 and 4.
