Canadian Researcher from the McGill University found that by listening to music, your brain releases dopamine, a “feel-good” neurotransmitter.

Music that moves us emotionally activates the “feel-good hormone” dopamine at the emotional networks of the brain. They are mainly in the lower part of the forebrain, directly above the eye socket. The dopamine inhibits the anxiety centers in the almond kernels. These almond-shaped structures are located on the left and right inside of the brain. Among other things, they process emotions such as fear and anger. If they are inhibited, another part of the brain, the hypothalamus, emits less stress hormones. As a result, the blood pressure drops, and the heartbeat calms down.
