Really impressive use of the source material, it's clearly recognizable but I don't remember it been used this way, slowed down and forming a solid basis for an electro-pop song. I especially love the airy vocals! On the downside, I don't find the male vocals quite up to par, and the bass drum is pumping the rest of the mix uncomfortably. I don't think the piece is dragged down by these points though, and the unexpected but natural arrangement is something to raise your hat to.
edit: I'll add that on the second Leitbur track of the album, the male vocals are spot-on, although the bass drum is again quite uncomfortable. I'm pretty happy to hear another track immediately!
