In episode 4, at the end, the scene right before the credits when they're in the room with Maria standing in the corner singing.

Could anyone tell me the name of that song? I listened through all the tracks from the soundtrack for the Anime, but it wasn't on there..

I uploaded a short video of the part I'm talking about, if it helps

Umineko Song - YouTube (http://www.youtube.com/watch?v=fP784u0DQ_8)

Animu version not released, apparently. Original BGM: My Favorites Umineko BGM's - #2 Golden Slaghterer - YouTube (http://www.youtube.com/watch?v=aw5GRp1Ry0g)

Although it does make my soul cry and horribly angry that they didnt release the Anime version, the original is quite awesome.

You've stopped me from going completely insane over this, thank you... So much.
