Yet another q about song title

[Chomiqos]

Ok, first of all hello to all of you. I'm new here so excuse me if you'll get annoyed by this type of question.

I'm looking for the title of song played many times in the series but I havent found it on both of the OST. It's played for the first time in episode 02, between 19:20 and 20:40, around same time in ep 07 and later within the whole series. Anyone care to help?

Edit.
Here's a clip taken from ep 7:

Go to bleach Exile, musicdownloads, 1st OST and the track is called "Nothing To Be Explained"
(Though if I remember it right, the real name is nothing can be explained)
