Dance

Dancing into insanity, until you can't dance any more; that kind of dancing makes you completely exhausted. You always have fun while you're dancing to the beat, because when you dance to the beat you keep the rhythm of the music. When you listen to music, the music first goes into your feet, then slowly but steadily it reaches your ears; and that's why music makes us dance into insanity. Musical group train to keep the rhythm, because musical group are very popular when they know how to keep the beat.
If the beat is good soon people will enjoy listening to the music. If people like what the musical group sings, they will buy the group's CDs until the group forget how to keep the beat, or until the group decides to quit singing. When a group quits singing, that just means the musicians are tired of singing with each other and want to move on to something else.
