Think about it for a few minutes. How many sense do you have? Sight, hearing, touch, taste and smell.
How many of them get used when gaming?
Smell and taste don't. Touch (sort) of does, with force-feedback effects. Sometimes.
So that really just leaves sight and sound. If you've only got two sense to respond to stimuli from a game, losing (or disliking, even worse) one of them is really going to damage the immersion you feel, or your sense of enjoyment.
I'll add Tenpei Sato (the composer of all the Disgaea music) to the list of great game music composers. His variety is superb, and I've not enjoyed a game soundtrack as much as Disgaea since Final Fantasy VIII and IX.

The Hitman music is great, as is C&C/C&C:RA.

I don't wanna say the series would be bad without him, as Square has an amazing lineup of composers (Yoko Shimomura, Yasunori Mitsuda, etc.), but it certainly wouldn't have been the same.
Final Fantasy IX is by far my favorite video game OST. It's about as close to perfect as a soundtrack can be IMO.
This is a perfect example of how a good soundtrack can take me through a game I otherwise wouldn't play. I didn't really like FFIX all that much, but the music! Oh, the music... that kept me playing by itself.
When Square started using people other than Uematsu as composers for FF music, I started to struggle. FFXII I didn't like for multiple reasons, but the music is one. Same with FFXIII and X-2 - Uematsu either had help, or was replaced entirely...
