The entire physical universe is made up of pure energy and vibration. When you have the insight to see everything as vibration, the nature of the universe is revealed to you.
Sound is vibration. Bassy music is low vibration and energetic music is high vibration. We enjoy listening to different types of music because we like to experience different ranges of emotion. The variety of feelings in life makes it fun and meaningful. High energy dance music appeal to younger people because they are highly energetic and expressive. Slower and emotional entrancing music is what we desire to hear when we want to be moved in a deep and sensual way. We want time to slow down and come to a standstill the experience to be like an eternal moment.
