Well, it's not in there, so it could be put up. Rob will make his decision when he gets home.
Yeah, I wish El-Hazard had something like that. The closest thing is taking advantage of the fact that 5.1 sound -- not available on anything other than the original OAV, unfortunately -- typically carries the primary voices on the "Center" channel... if you listen in on all channels but, you typically can get background noise or BGMs, depending on how its wired. It works for BTTF and El-Hazard at least! I still have a few private MP3s that at least have sections of unreleased music via that method, including some of the more interesting theme variations played at different parts of the show.
Ah yes, you mean Jinnai's Magnificent 5.1? That was pretty creative.
Yeah, that one wasn't soundtracked either. I like it too. But it's more like cause it sounds "boss of the game"-ish, and I have a kick of applying BGMs to video game type scenarios. Some facet of me, don't worry about it.
