nothing else matters

Can someone enlighten me on the subject of the TANGO OBSESSION with the song "Nothing Else Matters"??


Here is a video of Junior Carvalho and Mabel Rivero dancing to "Nothing Else Matters":

And here we have Daniela Pucci and Luis Bianchi dancing to... "Nothing Else Matters":

And my absolute favourite is the video of Ismael Ludman and Maria Mondino dancing to... Nothing Else Matters (Metallica).  I have this video on my computer, but it was given to me under strict confidence that I would NOT publish it... I searched all over the internet for it but alas, it doesn't appear to be published.  

Tonight in my class, which was a basic review of close embrace & ochos, the instructor played one song for us to practice to for an hour and a half.  Can you guess what it was??  NOTHING ELSE MATTERS!!  Has anyone else encountered this song over and over and over again in the exclusive and eccentric world that is the Argentine tango?  Please, someone enlighten me!

And because I robbed you of Ismael y Maria (who are my absolute favourite tango couple ever) dancing to this mysterious song, here is another video for you to enjoy.  I love watching them dance because they are so theatrical, their technique is practically perfect, they happily dance to electronic tango, and yet remain so faithful to the spirit of tango that it makes me want to cry (with joy).  Before I go on too long...

Well, I'm off to write a paper on the Hypostasis of the Archons... Gnosticism.  Wish me luck.  Maybe I can relate it to nothing else matters??  Oh wait, that's just tango...
