Many if they ride public transportation carry walkmans, cause I see these little ear pieces stickin in their ears. In the work place they play music to motivate you to do the work they want. If they are really good they will match the rhythm of the music to the rhythm of the workers and their work. If you go shopping they greet you with songs that fire you up and make you want to spend money. They play the music for the clientele they want to attract.
Restaurants play music to eat to or drink to.
A new hillbilly terminology. The rhythm of our souls is that clock that ticks within each of us. When it comes to dance it is that one special slow song to dance to that is not too fast or too slow, but that one which is just right, guess what time the bpm of the song, time your heart rate, bet they will match. When you have that special line dance that cranks, odds on it has a high enough energy to it to get your heart rate up to match the bpm of the song. Thats when you are in sync with the universe by which all time is recorded.
