If you are having fun dancing tango then you're not listening to the music
(or you have a weird definition of fun but i suspect that quite a few people here are masochists)
there are two tangos which are fun:
Gato and Espiante
the rest are full of existential anxst, tales of sorrow, unrequited love and how even my no-good dog has left me etc etc.
Lhasa said that listening to really sad songs make her happy. I'm a bit like that.
