I have already looked on this site for any of the soundtracks to this anime series and i couldn't find results. I was wondering if someone could put some of the soundtracks on to this site please.

I second that.

Complete music box is here. Some links are broken, but you can find those over here:

But if you just want to listen to the music you can go here:

It's a shame that it's so hard to find stuff for this show. Anything that's not already hard to find on the internet is very expensive to try to buy.

Some of my personal favorite tracks from UY, some from the movie theme songs, some series bgm and some from the Lum's Jukebox:
