Quick and dirty audio editting advice?

So I’ve got a stupidly geeky need* for a pumped up version of “A Warm Place” by Nine Inch Nails. I realize the futility in this, since the song is by nature pretty sedate, and I have pretty limited musical talent. I’ve found several remixes of the song, including a drum and bass mix that’s close to what I’m looking for, but not quite.

I downloaded some free audio mixing software and tried just speeding it up, but when I got the main part of the song to the right speed, the drum and bass track was too fast. I wish I could isolate the drum and bass track, but the software I was using didn’t seem to be able to.

And ideas?
*It’s the theme song of a recurring character in my D&D campaign and I want to be ready when the players fight him.

I don’t usually correct my typos, but that one’s particularly crytic.

“And ideas?” --> “Any ideas”
