"Communication between the brain’s auditory and reward circuits is 
the
reason why humans find music rewarding, according to new research
published in JNeurosci. 
It came even to pass, as the trumpeters and singers were as one,
*Despite no obvious biological benefits, humans love music.
Neuroimaging studies highlight similarities between how the brain’s
reward circuits process music and other rewards......Yet neuroimaging studies are correlational by nature.
---Exciting the reward circuit prior to hearing music increased the
pleasure participants felt when listening to the songs, while inhibiting
it decreased pleasure.
These induced pleasure changes were linked to
changes in activity in the nucleus accumbens, a key region of the reward
circuit.
---The participants with the greatest difference in pleasure also
showed the greatest difference in synchronized activity between
auditory and reward regions.
---These results indicate interactions between auditory and reward regions drive the pleasure we feel when listening to music." SciTechDaily
to make one sound to be heard in praising and thanking the LORD;
and when they lifted up their voice with the trumpets and cymbals and instruments of music, and praised the LORD, saying,
For he is good; for his mercy endureth for ever... I will praise thee; for I am fearfully and wonderfully made...
2 Chronicles 5:13/Psalm 139:14
