Luckily, we don't have to choose one or the other to dance forever!
"To fully understand poetry, we must first be fluent with its meter, rhyme, and figures of speech. Then ask two questions: One, how artfully has the objective of the poem been rendered, and two, how important is that objective. Question one rates the poem's perfection, question two rates its importance. And once these questions have been answered, determining a poem's greatness becomes a relatively simple matter."
Lets think about what Zoo said above: the joy of dance is to "...discover both the music and each other"
I think there are are two different things to discover about each other (and ourselves) - our musicality, our personal relationship and interpretation of the music, and our physicality, our mastery of our bodies and the physics of dance.
I think we can thing of dance as a mixture of these two goals.
If we want to explore our individual and shared relationship with the music we need a certain degree of complexity in the music -it is about us dealing with the flow of the music as a gestalt, and we need to use vocabulary that is very in the moment to allow us to work together on any changes of the music, and surprises that our partner offers in their interpretation of the music.
If we want to explore our individual and shared relationship with we need a certain degree of complexity in the movement vocabulary - it is about us overcoming/playing with physics using strength, timing and teamwork, and we need to use music that does not get into the way of that - we are working together through movement puzzles, and the music should not distract from that.
And a lot of electro tango that gives us a strong, reliable beat, and does not distract from that allows us to play with things are chained 5, 6, ten, howevermany steps, there will never be a moment where we will feel "i really should have hit that phrasing", or "we are getting back to the A part - i wonder if my partner thinks about this the same way as the first time?" or "why is there a break here" - it is in some sense more supportive of exploration of movement - we can follow our partners physicality instead of their musicality.
