Science of music

Based on MRI scans, they found that when people listened to music they liked, the limbic and paralimbic regions of the brain became more active. They’re the areas linked to euphoric reward responses, the same ones that bring the dopamine rush associated with food, sex and drugs. (Right, so throw in rock and roll.)

if a song turned out better than they had expected, based on pattern recognition, they wanted more of it.
