Did you just link EXEC_PURGER/. on a Final Fantasy website? New favorite. (Though I still prefer Aurica's version for that particular track. Misha's is a bit vanilla for Akiko Shikata. /heresy)

But seriously, Uematsu's composition style is what's known as "just winging it," and he had 10+ years of it under his belt before FFVI came along. I think Soken deserves some slack for not having mastered "just winging it" in his first major solo effort.
