Alright, I cant seem to find this music on either soundtrack (though I could easily be missing it), and Yahoo Answers hasn't been any help.

This clip has the music I'm lookin for:

Its also been used in the Japanese blu-ray commercials for Code Geass.

Can anyone ID it for me? Thanks for any help yall can give me.

I don't know about the Code Geass soundtrack, but maybe you could just DL the music using Vixy (http://vixy.net/)? Paste the video URL into the text field and select MP3 (audio only).

Here (http://www.johntp.com/2007/04/12/how-to-extract-audio-from-youtube-videos/)'s a tutorial.

It's track 20 on the second OST of the first season, titled "Avalon."

The only time I will ever advertise this website's services is in reference to its music collection:
