I'm really sorry if this isn't supposed to be posted here or if I wasn't supposed to create a new thread... but I didn't know where else to post this. Trying to find this song has been driving me crazy for the past week..

There's this song that's played in the very beginning of episode 23 of Kekkaishi (Right at the beginning of the show and before the opening, I think Gen Shishio is talking to Yoshimori and Tokine) ANYWAYS! I've searched through every song on the OST and the OP/ED soundtracks and have yet to find it anywhere. I don't know if I'm just stupid and totally missed it or what .. So my question is, are there missing songs from the OST and if so, what are they? I really like the song mentioned earlier and really want to listen to it. So any help would be appreciated
