You're right ! Composition is outstanding, but the sounds are really rough, like Roland/Korg expanders controlled through MIDI without much more. The voice samples in #2 are a bit more interesting, but I have no idea if they mean something in some language.
Searching for songs with this score quality often lead to higher quality sound production, and seaching for songs with those plain Roland-ish sounds leads to generic/bad compositions... (that's what I noticed by listening to hundred of various OSTs...)
