Why Music Rocks

Have you ever wondered why you nod your head during certain songs, or tap your feet for others? Me too. My 1 year old daughter and I were listening to music on Comcast, while playing. During the song Paralyzer, by Finger Eleven, I realized that my head was nodding to the beat. Then I looked over and noticed that my daughter was doing the same thing. She was not facing me, so I know that it was a reaction to the song and not a reaction to what I was doing. It must be the song.
