I was listening to the first Spyro soundtrack today, and actually noticed that, the beginning of
Stone Hill is actually the ICELAND 1 sample from Spectrasonics' Distorted Reality (aka the ambiance in
"End" (or as some like to call it; Last/Final Day/Hours, etc...) from Majora's Mask).
Some more:
The Bouncer- "RETRO HIT1" from "Spectrasonics: Distorted Reality 2" was used in 2.11 "無月-崩壊-"
Resident Evil (Nintendo GameCube)- "MYST GLASS" from "Zero-G: Ambient" was used in 4.26 "Deception" (track number and title from the box) (0:04)
