Music: Biology or Chemistry?

We can't say whether creation of music has anything special to do with emotion though I am inclined to believe that music listening has something to do with our emotional states. There too, it's a fact that relating certain music to certain moods or emotions is the result of a habitual listening. Yesterday I happened to talk to a friend about theories of emotions in the context of history of music listening. I remember reading an article which dealt with biological responses of the brain while listening to music. If you are trained in music, how do your brain relates to it? Let me quote from the article:
"Once again, there was a bias towards the right hemisphere—at least among those with no musical training. In such non-musicians, blood flow to the right hemisphere increased on exposure to music with a lot of harmonic intervals. (The researchers picked a 16th-century madrigal whose words were in Latin, a language chosen because it was not spoken by any of the participants, and so would not activate speech processing.) In musicians, however, the reverse was true; blood-flow increased to their left hemispheres, suggesting that their training was affecting the way they perceived harmony" ( http://www.economist.com/node/329414?Story_ID=329414)

Please listen to Madurai Somasundaram (who is known for the 'emotional' content in his music) singing Sindhu Bhairavi
