Yuki usually is composing very good / godly tracks but there are some tracks that I dont like, for example:
Obsession (.hack//SIGN) - I like the /Strings version)
0&1 city (Tsubasa chronicle)
There are more but I cant remember them right now (probably because I never listen to them) Ι hope that Yuki will continue composing godly tracks
Anyway its is natural for a composer to have some bad tracks. what matters is the percent of the good tracks he or she makes and Yuki has high good track percent. :D
I can't say that I dislike certain tracks, though when in one mood, I like certain tracks while some others leave me indifferent... And with a change in mood it all goes vise versa.That depends.
As for Obsession, I like the tv mix - the original gets me a bit puzzled about its structure. :)
