man..there are lot's of songs in the anime that isn't on the OST 1 or 2 i bet there will come a OST 3 soon i hope!!!!!!
the best song ever in the whole anime must be strong and strike or raising fighting spirit but i also love the shikamaru theme...it comes up while fighting that sound (excuse me) bitch and Temari
also sadness and sorrow is good and loneliness...they're wonderful
