I agree with Gilgamesh (apart for Final Fantasy X which I thought had a very good soundtrack). Nobuo Uematsu's music was a really big part of Final Fantasy. In fact, it's the only video game music I love enough to have on my iPod and listen to everyday.
I've just finished Final Fantasy XIII-2 and there's some pretty horrible tracks on there. Mostly, the ones that I can't stand are the lifeless dull "lounge" tracks that play in many locations and to make matters worse they added sleep-inducing vocals to go over these tracks which really irritates me.
Signature goes here!
