Final Fantasy 9? Frankly most videogame music after 1995 isn't really that good to me. Nobou Uematsu just seems to be wearing a bit thin now. He just keeps rehashing his old good ideas to something that vaguely sounds "Final Fantasy" but ends up being not very memorable.
Best Final Fantasy music, Final Fantasy II. Best music overall, Megaman II. Its been years and I can still hum all the tunes from it.
