I like some western composers.  But the problem is, they tend to either work on very specific projects or I've heard AMAZING works from composers...but for only one game.  I can name dozens of games that had great OSTs...but I can't trace their composers to other works.

Just wanted to say that Kondo DID NOT compose this song. His apprentice did, Mahito Yokota. Surprisingly, I learned this from a member here (can't remember his name, but he usually knows what he's talking about).

Jap:

YOKO SHIMOMURA!!! (Worked on Kingdom Hearts games and is currently working on Final Fantasy Versus XIII and Xenoblade. Her music is BEYOND AMAZING in my tastes)

Nobuo Uematsu (His Final Fantasy Pieces are pure Amazement)

The following are people that I can't remember their names but I'll list what they've worked on.
The Composer who composed half the music for Metal Gear Solid Peace Walker
The Composers who composed music for Metal Gear Solid 1, 2, 3 and 4
The Composers who's music were featured in Super Smash Bros Brawl. The Main Theme of Brawl is just EPIC and I still listen to it
The Composer who composed the music for Street Fighter IV and Super Street Fighter IV

Western:
Hans Zimmer (Worked on several big hit movies and worked on Modern Warfare 2 OST)
The Other Composer who composed the music for MGS 4
The Composers who worked on all the God of War I, II and III music

Ya, Martin O'Donnell, I know you already said him, but i just want to rieterate the point of the fact of the matter that he is awsome in every way.

Stephen Root / Steve Emney (Burnout 2)
Martin Sommerville (Rollcage)
Masafumi Takada (Loads of stuff for Grasshopper Manufacture)

Its true.  The only songs Kondo wrote for Galaxy was the theme for the Comet Observatory (the song you hear in the main Comet Observatory hub) and the song for the Egg Planet Galaxy.

Morrowind
KotOR
Oblivion
MGS: Peace Walker

I thought Kondo composed three songs - Good Egg, Gusty Garden and the Observatory theme? I know Yokota did the rest.
