Howl's Moving Castle: Merry-Go-Round (A beautiful instrumental theme in Howl's Moving Castle which could only be created by the one and the only persno who created Howl's Moving Castle...confusing you yet?)
Tsubasa: Fai's theme (Fai is an ultra cool person and the theme did fit his strange nature)
Inuyasha: Rakuen (Do As Infinity FTW)
Loveless: Michiyuki (Represents the manga AND anime VERY well)
Full Metal Alchemist: Lost Heaven (The meaning itself is beautiful. A lost Heaven...true to most people out there)
Ruroni Kenshin: Heart of the Sword (The beat just gets me hyped up)
Detective Conan: (old school but...) Step by Step
Samurai Champloo: Shiki no Uta (FTW)
Cowboy Bebop: The Real Folk Blues (Beautiful work with Cowboy Bebop. Just like Shiki no Uta, he has successfully made jazz and pop into a whole new genre)
Gundum Seed (Destiny?): Anna ni Isho Datta you ni (The one with no words and the violin sounds much better than the ones with words
)
Bleach: Thank You! (Again, Loving the whole jazzy FEELING)
DNAngel: True Light (the beginning is the best part of course...the melody of the piano took me over)
