A guy I sometimes dance with... has some decent technique and skills. When practicing without music, he's great to dance with. But, when it comes to the actual music...it is like what I'm hearing is not playing in his head. It is always faster than the actual rhythmn of the song...I end up feeling like I was just dragged around. So...I think having rhythmn is a very important thing. It's kind of like people that are tone-deaf. They can try and try but never sing a song on key although they think they are doing it correctly. One of those mysteries of life I guess.
