Still looking for this one... since I've heard some Underworld stuff on here, it sounds remotely similar, but don't hold me to it (I'm not a big Underworld expert)
That one is pretty obscure - It is called "Ion" by Placebo. One of their rare B-Sides, I think.
47:15 - 47:43 - Placebo - Ion
52:50 - 53:03 - Placebo - Ion
55:39 - 55:55 - Placebo - Ion
