I may have missed some things, so you should probably all check out this library. Also, CD1 track 15 reminds me of something, but I can't place it. Could be something unrelated to SH though.
Thanks to TechnoMysterio @ VGMdb for bringing the library to my attention. I personally never expected to find SH samples in the Sound Series libraries.
