Music - Feels good again

Today I felt good and happy while coming back from office. I am hoping to get the same happy attitude everyday. Coffee and Music made my mind excited. Music!!! yes, while walking back to the hotel there a big drums party. The rhythm was good, felt like dancing. The sound was very much refreshing, now the question is how and why this happen to human mind. Even when i was there in uganda, I saw people start dancing whenever they here any kind of music.
