as far as I remember this tune is often played while gruntys are shown, and more specifically when Tsukasa's riding a grunty which sorta bumps into the wall. xD does anyone know what I'm talking about?
I do believe I know which one you're talking about but I do not believe it is on any of the soundtracks. So unless someone has recorded it I don't think you can get it. I wouldn't know how to even begin a search for said recording either. You're best bet is to record it. If you have audacity (freeware) and the ability to play dvds on your computer you should be able to get a stereo recording of it. Unfortunately this would have all the dialogue and sounds from the dvd in it. Sorry I couldn't be more helpful.
