Could find threads for best opening and ending but not for OST.
What are your favorite OSTs (not including Opening and Ending songs).
I love Abel's Harp from Saint Seiya, every time I hear it brings nostalgia from my childhood.
The other harp songs (Orfeo's and Mime's) are also excellent.
Also love every Clannad song but one of my favorites is Snowfield
If there actually was another thread for this and my searching abilities are that of Zaraki, forgive me mods!
