yea its been up for a while but do u know if anybody has many collections of them, or if there any more sites?

Yeah, I have alot of the soundtracks. I should post em sometime.

Really? that would great thanks

If i'm not mistaken GH has some Tenchi Soundtracks too, mainly the first two OVAs I think. But you may have already checked that though.

...unless it under an odd name, but I'm guessing the Tenchi in Tokyo one isn't there...? God knows why I like that one =P

I have at least one Tenchi In Tokyo track somewhere on my PC. It's called "Yuugi" It's that evil girl's theme and it's about 5:00 mins long. But that's about the only song from the OST that i've ever found, I'll have to search for the rest.
