As a swing dancer and a hip-hop dancer I'm ambivalent about how hip-hop music is used in West Coast Swing.
On the one hand, I'm impressed with the difficulty in the choreography and cleverness of the moves. But on the other hand, I find the "up"-ness of WCS and the smoothness of the movement to be totally incongruent with the heavy beats and staccato patterns in hip-hop music. It just looks wrong to me.
But clearly I'm in the minority, based on how the crowds at WCS events appreciate and love these performances. What do you think?
