Gyegh...
The rock-techno, while I'm not judging on that, didn't quite fit it. The beat of the song is generally a little too slow for for the guitar renditions to turn out well; that's what I'm judging on. While it is a remix, it's too far from the original to in terms of beat. We've inserted an 8:4 timing in a classical; The original may have been 3:4. Slow, and the beat doesn't multiply evenly.
Oftentimes, the guitar overpowers the background instruments with this one, to the point where everything else playing alongside is utterly insignificant.
