A few points.
First, I know that's what a theme is supposed to do (bits and pieces being dropped here and there), I was just pointing out that I thought one of the tracks was the same one which was pre-released.
As for the combat music, I can definitely see how you're trying to get adrenaline pumping with the um... attacks, I think (not that good on music/sonic terminology), I just found it a bit... annoying, that's all. Don't be discouraged, though, once I manage to play UE a bit more, it might 'grow' on me, especially since it's quite catchy.
Just to illustrate, I recently bought Linkin Parks' Reanimation, and I was a bit disappointed at first at how much some of the songs had changed from the originals, but eventually they 'grew' on me too.
I don't see ripping the tracks is illegal, though, since it's only for my personal use, it's not like I'm selling them. It's just the same as ripping music from any other game I own, not to mention that UE is free to begin with, right?
And yes, I know the MGIs only sample at 22 kHz. My loss, no doubt, but all the other WC music samples at 22 kHz at most as well.
