Do you dance only to the beat or do you change the beats of your dance according to the melody?
It occurred to me listening to something like Tatu (All the Things She Said) that dancing to the beat can be boring. There's a beat there - but the changes in rythmn and tempo are far more interesting (IMO) and open to more interpretation on the dance floor.
You can 'find' a regular beat in anything if you try hard - from tango to salsa (ceroccers do it regularly in salsa clubs

) - but a regular beat can be very undemanding
(This is my first shot at a poll, so if I get shot down in flames or no-one replies I'll pick up that I haven't quite got DS's touch at it yet
