I don t remember in which episode I heard it first,but I know that I heard it again in episode 63,after the first half of the episode when Sh?hei Hisagi talks with the 7 division captain about recovering Tosen.Does anyone know what s the name of the song?

It's from Bleach's first OST- called creeping shadow.

I m sorry but it s not that.I ve checked it but I m sure it s not that,it sounds a little peaceful and sad.
