So many times, a band plays only for "themselves", rather than playing music for the dancers. It is unfortunate if you are there to "dance", and the band plays for themselves. Those type bands probably won't change their style. However, if you are a "ballroom" dancer, you should be able to dance to almost any type music as long as you can hear the beat. It may not be the best music in the world with which to dance, but you COULD do it.
If it were me, and if there is a dance floor, which implies that the music is there for dancers, and I am there to "dance", then I usually do not return if the band does not play for the dancers.
A "good" band along with a dance floor, even if small, will try to attract "dancers". That makes for return customers. Otherwise, if you are there to dance, and the music doesn't make you WANT to dance, then don't go there any more, don't waste your time. Right JJ?
