I agree with Steph's review. :P
This 7 is more of a 6.5 in my opinion. It's a neat song to listen to, but something about it just seems very odd. It's like when everything comes together (notice I have no technical terms because I don't know the technical stuff about music) it just seems very out of place and awkward.
I kind of like where you said, "I don't expect everyone to like it, as this is hard for the ears." :P It's not that it was hard on the ears, but it was very different. It's probably only seems out of place to it's listeners because it's not really something we've heard before.
While it does seem to be a little off it seems fitting to be used in small portion of flash games or movies. Perhaps during a time of anguish or in a dangerous situation. (That might seem weird though because a Tango is usually about fun and/or love and this song doesn't seem to fit that theme)
