Rock Quote of the Day "Each tune has a degree of stimulation programmed against the workers' fatigue curve. If you were listening to music at 70 beats per minute it would do nothing for you because that's your pulse rate. It would neither soothe nor stimulate you. In fact we never go below 70 beats because we are not interested in soothing people or putting them to sleep." - Lee Valvoda (executive, Muzac Corporation)
