One of the best Saint Seiya songs, it is not in the anime but it is in the OST

Andromeda Symphonic Experience | Abel's Theme

Inspired from the first Saint Seiya OVA: Shinku No Shunen Densetsu and with the art from the japanese cartoonist Michi Himeno which appears on the cover of the Bandai Myth Cloth from Abel and Saori figures, this canvas and this iconic song plays the harp as the main instrument and make us remember the paceful time between this god brothers.
